    Bug Fix(es):

    * proxy rewrite to unix socket fails with CVE-2021-40438 fix (BZ#2022319)

    Additional changes:

    * To fix CVE-2022-29404, the default value for the LimitRequestBody directive in the Apache HTTP Server     has been changed from 0 (unlimited) to 1 GiB.

    On systems where the value of LimitRequestBody is not explicitly specified in an httpd configuration     file, updating the httpd package sets LimitRequestBody to the default value of 1 GiB. As a consequence,     if the total size of the HTTP request body exceeds this 1 GiB default limit, httpd returns the 413 Request     Entity Too Large error code.

    If the new default allowed size of an HTTP request message body is insufficient for your use case, update     your httpd configuration files within the respective context (server, per-directory, per-file, or per-     location) and set your preferred limit in bytes. For example, to set a new 2 GiB limit, use:

    LimitRequestBody 2147483648

    Systems already configured to use any explicit value for the LimitRequestBody directive are unaffected     by this change.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

According to the versions of the httpd packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - A crafted URI sent to httpd configured as a forward proxy (ProxyRequests on) can cause a crash (NULL     pointer dereference) or, for configurations mixing forward and reverse proxy declarations, can allow for     requests to be directed to a declared Unix Domain Socket endpoint (Server Side Request Forgery). This     issue affects Apache HTTP Server 2.4.7 up to 2.4.51 (included). (CVE-2021-44224)

  - A carefully crafted request body can cause a buffer overflow in the mod_lua multipart parser     (r:parsebody() called from Lua scripts). The Apache httpd team is not aware of an exploit for the     vulnerability though it might be possible to craft one. This issue affects Apache HTTP Server 2.4.51 and     earlier. (CVE-2021-44790)

  - A carefully crafted request body can cause a read to a random memory area which could cause the process to     crash. This issue affects Apache HTTP Server 2.4.52 and earlier. (CVE-2022-22719)

  - Apache HTTP Server 2.4.52 and earlier fails to close inbound connection when errors are encountered     discarding the request body, exposing the server to HTTP Request Smuggling (CVE-2022-22720)

  - If LimitXMLRequestBody is set to allow request bodies larger than 350MB (defaults to 1M) on 32 bit systems     an integer overflow happens which later causes out of bounds writes. This issue affects Apache HTTP Server     2.4.52 and earlier. (CVE-2022-22721)

  - Out-of-bounds Write vulnerability in mod_sed of Apache HTTP Server allows an attacker to overwrite heap     memory with possibly attacker provided data. This issue affects Apache HTTP Server 2.4 version 2.4.52 and     prior versions. (CVE-2022-23943)

  - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') vulnerability in mod_proxy_ajp of     Apache HTTP Server allows an attacker to smuggle requests to the AJP server it forwards requests to. This     issue affects Apache HTTP Server Apache HTTP Server 2.4 version 2.4.53 and prior versions.
    (CVE-2022-26377)

  - The ap_rwrite() function in Apache HTTP Server 2.4.53 and earlier may read unintended memory if an     attacker can cause the server to reflect very large input using ap_rwrite() or ap_rputs(), such as with     mod_luas r:puts() function. Modules compiled and distributed separately from Apache HTTP Server that use     the 'ap_rputs' function and may pass it a very large (INT_MAX or larger) string must be compiled against     current headers to resolve the issue. (CVE-2022-28614)

  - Apache HTTP Server 2.4.53 and earlier may crash or disclose information due to a read beyond bounds in     ap_strcmp_match() when provided with an extremely large input buffer. While no code distributed with the     server can be coerced into such a call, third-party modules or lua scripts that use ap_strcmp_match() may     hypothetically be affected. (CVE-2022-28615)

  - In Apache HTTP Server 2.4.53 and earlier, a malicious request to a lua script that calls r:parsebody(0)     may cause a denial of service due to no default limit on possible input size. (CVE-2022-29404)

  - If Apache HTTP Server 2.4.53 is configured to do transformations with mod_sed in contexts where the input     to mod_sed may be very large, mod_sed may make excessively large memory allocations and trigger an abort.
    (CVE-2022-30522)

  - Apache HTTP Server 2.4.53 and earlier may return lengths to applications calling r:wsread() that point     past the end of the storage allocated for the buffer. (CVE-2022-30556)

  - Apache HTTP Server 2.4.53 and earlier may not send the X-Forwarded-* headers to the origin server based on     client side Connection header hop-by-hop mechanism. This may be used to bypass IP based authentication on     the origin server/application. (CVE-2022-31813)

An update of the httpd package has been released.

According to the versions of the httpd packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - Apache HTTP Server versions 2.4.0 to 2.4.46 A specially crafted Digest nonce can cause a stack overflow in     mod_auth_digest. There is no report of this overflow being exploitable, nor the Apache HTTP Server team     could create one, though some particular compiler and/or compilation option might make it possible, with     limited consequences anyway due to the size (a single byte) and the value (zero byte) of the overflow     (CVE-2020-35452)

  - Apache HTTP Server versions 2.4.0 to 2.4.46 A specially crafted Cookie header handled by mod_session can     cause a NULL pointer dereference and crash, leading to a possible Denial Of Service (CVE-2021-26690)

  - In Apache HTTP Server versions 2.4.0 to 2.4.46 a specially crafted SessionHeader sent by an origin server     could cause a heap overflow (CVE-2021-26691)

  - Malformed requests may cause the server to dereference a NULL pointer. This issue affects Apache HTTP     Server 2.4.48 and earlier. (CVE-2021-34798)

  - ap_escape_quotes() may write beyond the end of a buffer when given malicious input. No included modules     pass untrusted data to these functions, but third-party / external modules may. This issue affects Apache     HTTP Server 2.4.48 and earlier. (CVE-2021-39275)

  - A crafted request uri-path can cause mod_proxy to forward the request to an origin server choosen by the     remote user. This issue affects Apache HTTP Server 2.4.48 and earlier. (CVE-2021-40438)

  - A carefully crafted request body can cause a buffer overflow in the mod_lua multipart parser     (r:parsebody() called from Lua scripts). The Apache httpd team is not aware of an exploit for the     vulnerabilty though it might be possible to craft one. This issue affects Apache HTTP Server 2.4.51 and     earlier. (CVE-2021-44790)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2022-2022-110 advisory.

    An HTTP request smuggling vulnerability was found in the mod_proxy_ajp module of httpd. This flaw allows     an attacker to smuggle requests to the AJP server, where it forwards requests. (CVE-2022-26377)

    An out-of-bounds read vulnerability was found in the mod_isapi module of httpd. The issue occurs when     httpd is configured to process requests with the mod_isapi module. (CVE-2022-28330)

    An out-of-bounds read vulnerability was found in httpd. A very large input to the ap_rputs and ap_rwrite     functions can lead to an integer overflow and result in an out-of-bounds read. (CVE-2022-28614)

    An out-of-bounds read vulnerability was found in httpd. A very large input to the ap_strcmp_match function     can lead to an integer overflow and result in an out-of-bounds read. (CVE-2022-28615)

    A flaw was found in the mod_lua module of httpd. A malicious request to a Lua script that calls     parsebody(0) can lead to a denial of service due to no default limit on the possible input size.
    (CVE-2022-29404)

    A flaw was found in the mod_sed module of httpd. A very large input to the mod_sed module can result in a     denial of service due to excessively large memory allocations. (CVE-2022-30522)

    A flaw was found in the mod_lua module of httpd. The data returned by the wsread function may point past     the end of the storage allocated for the buffer, resulting in information disclosure. (CVE-2022-30556)

    A flaw was found in the mod_proxy module of httpd. The server may remove the X-Forwarded-* headers from a     request based on the client-side Connection header hop-by-hop mechanism. (CVE-2022-31813)

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-072 advisory.

    There's a null pointer dereference and server-side request forgery flaw in httpd's mod_proxy module, when     it is configured to be used as a forward proxy. A crafted packet could be sent on the adjacent network to     the forward proxy that could cause a crash, or potentially SSRF via misdirected Unix Domain Socket     requests. In the worst case, this could cause a denial of service or compromise to confidentiality of     data. (CVE-2021-44224)

    A buffer overflow flaw in httpd's lua module could allow an out-of-bounds write. An attacker who is able     to submit a crafted request to an httpd instance that is using the lua module may be able to cause an     impact to confidentiality, integrity, and/or availability. (CVE-2021-44790)

    A flaw was found in the mod_lua module of httpd. A crafted request body can cause a read to a random     memory area due to an uninitialized value in functions called by the parsebody function. The highest treat     of this vulnerability is availability. (CVE-2022-22719)

    A flaw was found in httpd. The inbound connection is not closed when it fails to discard the request body,     which may expose the server to HTTP request smuggling. (CVE-2022-22720)

    A flaw was found in httpd, where it incorrectly limits the value of the LimitXMLRequestBody option. This     issue can lead to an integer overflow and later causes an out-of-bounds write. (CVE-2022-22721)

    An out-of-bounds read/write vulnerability was found in the mod_sed module of httpd. This flaw allows an     attacker to overwrite the memory of an httpd instance that is using mod_sed with data provided by the     attacker. (CVE-2022-23943)

    An HTTP request smuggling vulnerability was found in the mod_proxy_ajp module of httpd. This flaw allows     an attacker to smuggle requests to the AJP server, where it forwards requests. (CVE-2022-26377)

    An out-of-bounds read vulnerability was found in the mod_isapi module of httpd. The issue occurs when     httpd is configured to process requests with the mod_isapi module. (CVE-2022-28330)

    An out-of-bounds read vulnerability was found in httpd. A very large input to the ap_rputs and ap_rwrite     functions can lead to an integer overflow and result in an out-of-bounds read. (CVE-2022-28614)

    An out-of-bounds read vulnerability was found in httpd. A very large input to the ap_strcmp_match function     can lead to an integer overflow and result in an out-of-bounds read. (CVE-2022-28615)

    A flaw was found in the mod_lua module of httpd. A malicious request to a Lua script that calls     parsebody(0) can lead to a denial of service due to no default limit on the possible input size.
    (CVE-2022-29404)

    A flaw was found in the mod_sed module of httpd. A very large input to the mod_sed module can result in a     denial of service due to excessively large memory allocations. (CVE-2022-30522)

    A flaw was found in the mod_lua module of httpd. The data returned by the wsread function may point past     the end of the storage allocated for the buffer, resulting in information disclosure. (CVE-2022-30556)

    A flaw was found in the mod_proxy module of httpd. The server may remove the X-Forwarded-* headers from a     request based on the client-side Connection header hop-by-hop mechanism. (CVE-2022-31813)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2022:0271 advisory.

    Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

      CVE-2022-28614:
      The ap_rwrite() function in Apache HTTP Server 2.4.53 and earlier may read unintended memory if an     attacker can cause the server to reflect very large input using ap_rwrite() or ap_rputs(), such as with     mod_luas r:puts() function. Modules compiled and distributed separately from Apache HTTP Server that use     the 'ap_rputs' function and may pass it a very large (INT_MAX or larger) string must be compiled against     current headers to resolve the issue.

      CVE-2022-28615:
      Apache HTTP Server 2.4.53 and earlier may crash or disclose information due to a read beyond bounds in     ap_strcmp_match() when provided with an extremely large input buffer. While no code distributed with the     server can be coerced into such a call, third-party modules or lua scripts that use ap_strcmp_match() may     hypothetically be affected.

      CVE-2022-30522:
      If Apache HTTP Server 2.4.53 is configured to do transformations with mod_sed in contexts where the     input to mod_sed may be very large, mod_sed may make excessively large memory allocations and trigger an     abort.

      CVE-2022-30556:
      Apache HTTP Server 2.4.53 and earlier may return lengths to applications calling r:wsread() that point     past the end of the storage allocated for the buffer.

      CVE-2022-31813:
      Apache HTTP Server 2.4.53 and earlier may not send the X-Forwarded-* headers to the origin server based     on client side Connection header hop-by-hop mechanism. This may be used to bypass IP based authentication     on the origin server/application.

      CVE-2022-29404:
      In Apache HTTP Server 2.4.53 and earlier, a malicious request to a lua script that calls r:parsebody(0)     may cause a denial of service due to no default limit on possible input size.

      CVE-2022-26377:
      Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') vulnerability in mod_proxy_ajp     of Apache HTTP Server allows an attacker to smuggle requests to the AJP server it forwards requests to.
    This issue affects Apache HTTP Server Apache HTTP Server 2.4 version 2.4.53 and prior versions.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of Tencent Linux installed on the remote TencentOS Server 2 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2025:0526 advisory.

    Package updates are available for TencentOS Server 2 that fix the following vulnerabilities:

    CVE-2006-20001:
    A carefully crafted If: request header can cause a memory read, or write of a single zero byte, in a pool     (heap) memory location beyond the header value sent. This could cause the process to crash.

    This issue affects Apache HTTP Server 2.4.54 and earlier.

    CVE-2020-35452:
    Apache HTTP Server versions 2.4.0 to 2.4.46 A specially crafted Digest nonce can cause a stack overflow in     mod_auth_digest. There is no report of this overflow being exploitable, nor the Apache HTTP Server team     could create one, though some particular compiler and/or compilation option might make it possible, with     limited consequences anyway due to the size (a single byte) and the value (zero byte) of the overflow

    CVE-2021-26690:
    Apache HTTP Server versions 2.4.0 to 2.4.46 A specially crafted Cookie header handled by mod_session can     cause a NULL pointer dereference and crash, leading to a possible Denial Of Service

    CVE-2022-22719:
    A carefully crafted request body can cause a read to a random memory area which could cause the process to     crash. This issue affects Apache HTTP Server 2.4.52 and earlier.

    CVE-2022-22721:
    If LimitXMLRequestBody is set to allow request bodies larger than 350MB (defaults to 1M) on 32 bit systems     an integer overflow happens which later causes out of bounds writes. This issue affects Apache HTTP Server     2.4.52 and earlier.

    CVE-2022-23943:
    Out-of-bounds Write vulnerability in mod_sed of Apache HTTP Server allows an attacker to overwrite heap     memory with possibly attacker provided data. This issue affects Apache HTTP Server 2.4 version 2.4.52 and     prior versions.

    CVE-2022-28615:
    Apache HTTP Server 2.4.53 and earlier may crash or disclose information due to a read beyond bounds in     ap_strcmp_match() when provided with an extremely large input buffer. While no code distributed with the     server can be coerced into such a call, third-party modules or lua scripts that use ap_strcmp_match() may     hypothetically be affected.

    CVE-2022-29404:
    In Apache HTTP Server 2.4.53 and earlier, a malicious request to a lua script that calls r:parsebody(0)     may cause a denial of service due to no default limit on possible input size.

    CVE-2022-30556:
    Apache HTTP Server 2.4.53 and earlier may return lengths to applications calling r:wsread() that point     past the end of the storage allocated for the buffer.

    CVE-2022-31813:
    Apache HTTP Server 2.4.53 and earlier may not send the X-Forwarded-* headers to the origin server based on     client side Connection header hop-by-hop mechanism. This may be used to bypass IP based authentication on     the origin server/application.

    CVE-2022-36760:
    Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') vulnerability in mod_proxy_ajp of     Apache HTTP Server allows an attacker to smuggle requests to the AJP server it forwards requests to.  This     issue affects Apache HTTP Server Apache HTTP Server 2.4 version 2.4.54 and prior versions.

    CVE-2023-31122:
    Out-of-bounds Read vulnerability in mod_macro of Apache HTTP Server.This issue affects Apache HTTP Server:
    through 2.4.57.

    CVE-2024-39573:
    Potential SSRF in mod_rewrite in Apache HTTP Server 2.4.59 and earlier allows an attacker to cause unsafe     RewriteRules to unexpectedly setup URL's to be handled by mod_proxy.
    Users are recommended to upgrade to version 2.4.60, which fixes this issue.

    CVE-2022-26377:
    Inconsistent Interpretation of HTTP Requests (/'HTTP Request Smuggling/') vulnerability in mod_proxy_ajp     of Apache HTTP Server allows an attacker to smuggle requests to the AJP server it forwards requests to.
    This issue affects Apache HTTP Server Apache HTTP Server 2.4 version 2.4.53 and prior versions.
