According to the version of the httpd packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  - A specially crafted HTTP request header could have     crashed the Apache HTTP Server prior to version 2.4.30     due to an out of bound read while preparing data to be     cached in shared memory. It could be used as a Denial     of Service attack against users of mod_cache_socache.
    The vulnerability is considered as low risk since     mod_cache_socache is not widely used, mod_cache_disk is     not concerned by this vulnerability.(CVE-2018-1303)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

An update of the httpd package has been released.

This update includes the latest upstream release of the Apache HTTP Server, version 2.4.33. A number of security vulnerabilities are fixed in this release :

  - *Low*: Possible out of bound read in mod_cache_socache     (CVE-2018-1303)

  - *Low*: Possible out of bound access after failure in     reading the HTTP request (CVE-2018-1301)

  - *Low*: Weak Digest auth nonce generation in     mod_auth_digest (CVE-2018-1312)

  - *Low*: <FilesMatch> bypass with a trailing newline in     the file name (CVE-2017-15715)

  - *Low*: Out of bound write in mod_authnz_ldap when using     too small Accept-Language values (CVE-2017-15710)

  - *Moderate*: Tampering of mod_session data for CGI     applications (CVE-2018-1283)

The remote Ubuntu 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3627-2 advisory.

    USN-3627-1 fixed vulnerabilities in Apache HTTP Server. This update provides the corresponding updates for     Ubuntu 18.04 LTS.

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

  - A specially crafted HTTP request header could have     crashed the Apache HTTP Server prior to version 2.4.30     due to an out of bound read while preparing data to be     cached in shared memory. It could be used as a Denial     of Service attack against users of mod_cache_socache.
    The vulnerability is considered as low risk since     mod_cache_socache is not widely used, mod_cache_disk is     not concerned by this vulnerability.(CVE-2018-1303)

  - In Apache httpd 2.0.23 to 2.0.65, 2.2.0 to 2.2.34, and     2.4.0 to 2.4.29, mod_authnz_ldap, if configured with     AuthLDAPCharsetConfig, uses the Accept-Language header     value to lookup the right charset encoding when     verifying the user's credentials. If the header value     is not present in the charset conversion table, a     fallback mechanism is used to truncate it to a two     characters value to allow a quick retry (for example,     'en-US' is truncated to 'en'). A header value of less     than two characters forces an out of bound write of one     NUL byte to a memory location that is not part of the     string. In the worst case, quite unlikely, the process     would crash which could be used as a Denial of Service     attack. In the more likely case, this memory is already     reserved for future use and the issue has no effect at     all.(CVE-2017-15710)

  - In Apache httpd 2.4.0 to 2.4.29, the expression     specified in could match '$' to a newline character in     a malicious filename, rather than matching only the end     of the filename. This could be exploited in     environments where uploads of some files are are     externally blocked, but only by matching the trailing     portion of the filename.(CVE-2017-15715)

  - In Apache httpd 2.2.0 to 2.4.29, when generating an     HTTP Digest authentication challenge, the nonce sent to     prevent reply attacks was not correctly generated using     a pseudo-random seed. In a cluster of servers using a     common Digest authentication configuration, HTTP     requests could be replayed across servers by an     attacker without detection.(CVE-2018-1312)

According to its banner, the version of Apache running on the remote host is 2.4.x prior to 2.4.33. It is, therefore, affected by multiple vulnerabilities:

  - An out of bounds write vulnerability exists in mod_authnz_ldap     with AuthLDAPCharsetConfig enabled. An unauthenticated, remote     attacker can exploit this, via the Accept-Language header value,     to cause the application to stop responding. (CVE-2017-15710)  
  - An arbitrary file upload vulnerability exists in the FilesMatch     component where a malicious filename can be crafted to match the     expression check for a newline character. An unauthenticated,     remote attacker can exploit this, via newline character, to     upload arbitrary files on the remote host subject to the     privileges of the user. (CVE-2017-15715)

  - A session management vulnerability exists in the     mod_session component due to SessionEnv being enabled and     forwarding it's session data to the CGI Application. An     unauthenticated, remote attacker can exploit this, via     tampering the HTTP_SESSION and using a session header, to     influence content. (CVE-2018-1283)

  - An out of bounds access vulnerability exists when the size limit     is reached. An unauthenticated, remote attacker can exploit this,     to cause the Apache HTTP Server to crash. (CVE-2018-1301)

  - A write after free vulnerability exists in HTTP/2 stream due to     a NULL pointer being written to an area of freed memory. An     unauthenticated, remote attacker can exploit this to execute     arbitrary code. (CVE-2018-1302)   
  - An out of bounds read vulnerability exists in mod_cache_socache.
    An unauthenticated, remote attacker can exploit this, via a     specially crafted HTTP request header to cause the application     to stop responding. (CVE-2018-1303)

  - A weak digest vulnerability exists in the HTTP digest     authentication challenge.  An unauthenticated, remote attacker     can exploit this in a cluster of servers configured to use a     common digest authentication, to replay HTTP requests across     servers without being detected. (CVE-2018-1312)

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