CVE-2023-45802 | 2 Apache, Fedoraproject | 2 Http Server, Fedora | 2023-11-07 | N/A | 5.9 MEDIUM |
When a HTTP/2 stream was reset (RST frame) by a client, there was a time window were the request's memory resources were not reclaimed immediately. Instead, de-allocation was deferred to connection close. A client could send new requests and resets, keeping the connection busy and open and causing the memory footprint to keep on growing. On connection close, all resources were reclaimed, but the process might run out of memory before that. This was found by the reporter during testing of CVE-2023-44487 (HTTP/2 Rapid Reset Exploit) with their own test client. During "normal" HTTP/2 use, the probability to hit this bug is very low. The kept memory would not become noticeable before the connection closes or times out. Users are recommended to upgrade to version 2.4.58, which fixes the issue. | |||||
CVE-2023-31122 | 2 Apache, Fedoraproject | 2 Http Server, Fedora | 2023-11-07 | N/A | 7.5 HIGH |

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-2022-30522 | 3 Apache, Fedoraproject, Netapp | 3 Http Server, Fedora, Clustered Data Ontap | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
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-2022-30556 | 3 Apache, Fedoraproject, Netapp | 3 Http Server, Fedora, Clustered Data Ontap | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
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-2022-29404 | 3 Apache, Fedoraproject, Netapp | 3 Http Server, Fedora, Clustered Data Ontap | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
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 | 3 Apache, Fedoraproject, Netapp | 3 Http Server, Fedora, Clustered Data Ontap | 2023-11-07 | 6.4 MEDIUM | 9.1 CRITICAL |
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 | 3 Apache, Fedoraproject, Netapp | 3 Http Server, Fedora, Clustered Data Ontap | 2023-11-07 | 5.0 MEDIUM | 5.3 MEDIUM |
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-2022-26377 | 3 Apache, Fedoraproject, Netapp | 3 Http Server, Fedora, Clustered Data Ontap | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
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. | |||||

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. | |||||

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. | |||||

CVE-2021-42013 | 4 Apache, Fedoraproject, Netapp and 1 more | 6 Http Server, Fedora, Cloud Backup and 3 more | 2023-11-07 | 7.5 HIGH | 9.8 CRITICAL |
It was found that the fix for CVE-2021-41773 in Apache HTTP Server 2.4.50 was insufficient. An attacker could use a path traversal attack to map URLs to files outside the directories configured by Alias-like directives. If files outside of these directories are not protected by the usual default configuration "require all denied", these requests can succeed. If CGI scripts are also enabled for these aliased pathes, this could allow for remote code execution. This issue only affects Apache 2.4.49 and Apache 2.4.50 and not earlier versions. | |||||

A carefully crafted request body can cause a buffer overflow in the mod_lua multipart parser (r:parsebody() called from Lua scripts). The Apache httpd team is not aware of an exploit for the vulnerabilty though it might be possible to craft one. This issue affects Apache HTTP Server 2.4.51 and earlier. | |||||

A crafted URI sent to httpd configured as a forward proxy (ProxyRequests on) can cause a crash (NULL pointer dereference) or, for configurations mixing forward and reverse proxy declarations, can allow for requests to be directed to a declared Unix Domain Socket endpoint (Server Side Request Forgery). This issue affects Apache HTTP Server 2.4.7 up to 2.4.51 (included). | |||||
CVE-2021-41773 | 4 Apache, Fedoraproject, Netapp and 1 more | 4 Http Server, Fedora, Cloud Backup and 1 more | 2023-11-07 | 4.3 MEDIUM | 7.5 HIGH |
A flaw was found in a change made to path normalization in Apache HTTP Server 2.4.49. An attacker could use a path traversal attack to map URLs to files outside the directories configured by Alias-like directives. If files outside of these directories are not protected by the usual default configuration "require all denied", these requests can succeed. If CGI scripts are also enabled for these aliased pathes, this could allow for remote code execution. This issue is known to be exploited in the wild. This issue only affects Apache 2.4.49 and not earlier versions. The fix in Apache HTTP Server 2.4.50 was found to be incomplete, see CVE-2021-42013. | |||||
CVE-2021-41524 | 4 Apache, Fedoraproject, Netapp and 1 more | 4 Http Server, Fedora, Cloud Backup and 1 more | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
While fuzzing the 2.4.49 httpd, a new null pointer dereference was detected during HTTP/2 request processing, allowing an external source to DoS the server. This requires a specially crafted request. The vulnerability was recently introduced in version 2.4.49. No exploit is known to the project. | |||||
CVE-2021-40438 | 7 Apache, Debian, F5 and 4 more | 14 Http Server, Debian Linux, F5os and 11 more | 2023-11-07 | 6.8 MEDIUM | 9.0 CRITICAL |
A crafted request uri-path can cause mod_proxy to forward the request to an origin server choosen by the remote user. This issue affects Apache HTTP Server 2.4.48 and earlier. | |||||
CVE-2021-39275 | 6 Apache, Debian, Fedoraproject and 3 more | 11 Http Server, Debian Linux, Fedora and 8 more | 2023-11-07 | 7.5 HIGH | 9.8 CRITICAL |
ap_escape_quotes() may write beyond the end of a buffer when given malicious input. No included modules pass untrusted data to these functions, but third-party / external modules may. This issue affects Apache HTTP Server 2.4.48 and earlier. |
