Vulnerabilities 10
-
Critical 9.1
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…
-
Unscored —CVE-2022-22719 EPSS 70%
mod_lua Use of uninitialized value of in r:parsebody
A carefully crafted request body can cause a read to a random memory area which could cause the process to crash. This issue affects Apache HTTP Server 2.4.52 and earlier.
-
Unscored —CVE-2022-22721 EPSS 42%
core: Possible buffer overflow with very large or unlimited LimitXMLRequestBody
If LimitXMLRequestBody is set to allow request bodies larger than 350MB (defaults to 1M) on 32 bit systems an integer overflow happens which later causes out of bounds writes. This issue affects Apache HTTP Server 2.4.52 and earlier.
-
Unscored —
mod_sed: Read/write beyond bounds
Out-of-bounds Write vulnerability in mod_sed of Apache HTTP Server allows an attacker to overwrite heap memory with possibly attacker provided data. This issue affects Apache HTTP Server 2.4 version 2.4.52 and prior versions.
-
Unscored —
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. This issue affects Apache HTTP Server Apache HTTP Se…
-
Unscored —
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. Modules compiled and distrib…
-
Unscored —
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.
-
Unscored —CVE-2022-30522 EPSS 90%
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.
-
Unscored —
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.
-
Unscored —CVE-2022-31813 Public exploit
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.
