The remote Ubuntu 16.04 ESM / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5487-3 advisory.

  - 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)

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

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:2338-1 advisory.

The version of Apache httpd installed on the remote host is prior to 2.4.54. It is, therefore, affected by multiple vulnerabilities as referenced in the 2.4.54 advisory.

  - Denial of Service mod_sed: 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.
