Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') vulnerability in modproxyajp 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) Apache HTTP Server 2.4.53 and earlier may crash or disclose information due to a read beyond bounds in apstrcmpmatch() 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 apstrcmpmatch() 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) 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)
