    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)

The remote host is affected by the vulnerability described in GLSA-202208-20 (Apache HTTPD: Multiple Vulnerabilities)

  - A crafted method sent through HTTP/2 will bypass validation and be forwarded by mod_proxy, which can lead     to request splitting or cache poisoning. This issue affects Apache HTTP Server 2.4.17 to 2.4.48.
    (CVE-2021-33193)

  - 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)

  - A carefully crafted request uri-path can cause mod_proxy_uwsgi to read above the allocated memory and     crash (DoS). This issue affects Apache HTTP Server versions 2.4.30 to 2.4.48 (inclusive). (CVE-2021-36160)

  - 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)

  - While fuzzing the 2.4.49 httpd, a new null pointer dereference was detected during HTTP/2 request     processing, allowing an external source to DoS the server. This requires a specially crafted request. The     vulnerability was recently introduced in version 2.4.49. No exploit is known to the project.
    (CVE-2021-41524)

  - A flaw was found in a change made to path normalization in Apache HTTP Server 2.4.49. An attacker could     use a path traversal attack to map URLs to files outside the directories configured by Alias-like     directives. If files outside of these directories are not protected by the usual default configuration     require all denied, these requests can succeed. If CGI scripts are also enabled for these aliased     pathes, this could allow for remote code execution. This issue is known to be exploited in the wild. This     issue only affects Apache 2.4.49 and not earlier versions. The fix in Apache HTTP Server 2.4.50 was found     to be incomplete, see CVE-2021-42013. (CVE-2021-41773)

  - It was found that the fix for CVE-2021-41773 in Apache HTTP Server 2.4.50 was insufficient. An attacker     could use a path traversal attack to map URLs to files outside the directories configured by Alias-like     directives. If files outside of these directories are not protected by the usual default configuration     require all denied, these requests can succeed. If CGI scripts are also enabled for these aliased     pathes, this could allow for remote code execution. This issue only affects Apache 2.4.49 and Apache     2.4.50 and not earlier versions. (CVE-2021-42013)

  - 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)

    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-2022-29404:
    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.
