The Apache httpd project reports:
- CVE-2022-31813: mod_proxy X-Forwarded-For dropped by hop-by-hop
mechanism. 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-2022-30556: Information Disclosure in mod_lua with websockets.
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-2022-30522: mod_sed denial of service. 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-2022-29404: Denial of service in mod_lua r:parsebody. 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-2022-28615: Read beyond bounds in ap_strcmp_match(). 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-2022-28614: read beyond bounds via ap_rwrite(). 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-2022-28330: read beyond bounds in mod_isapi. 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-2022-26377: mod_proxy_ajp: Possible request smuggling.
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.
