Apache 2.4.x < 2.4.54 Multiple Vulnerabilities

According to its banner, the version of Apache running on the remote host is 2.4.x prior to 2.4.54. It is, therefore, affected by multiple vulnerabilities:

• 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. (CVE-2022-26377)

• Apache HTTP Server 2.4.53 and earlier on Windows may read beyond bounds when configured to process requests with the mod_isapi module. (CVE-2022-28330)

• 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. (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 the scanner has not tested for these issues but has instead relied only on the application’s self-reported version number.
