| CVE-2021-41773 | 4 Apache, Fedoraproject, Netapp and 1 more | 4 Http Server, Fedora, Cloud Backup and 1 more | 2025-03-21 | 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-2024-38477 | 2 Apache, Netapp | 2 Http Server, Clustered Data Ontap | 2025-03-18 | N/A | 7.5 HIGH |
| null pointer dereference in mod_proxy in Apache HTTP Server 2.4.59 and earlier allows an attacker to crash the server via a malicious request. Users are recommended to upgrade to version 2.4.60, which fixes this issue. | |||||
| CVE-2024-40725 | 1 Apache | 1 Http Server | 2025-03-14 | N/A | 5.3 MEDIUM |
| A partial fix for CVE-2024-39884 in the core of Apache HTTP Server 2.4.61 ignores some use of the legacy content-type based configuration of handlers. "AddType" and similar configuration, under some circumstances where files are requested indirectly, result in source code disclosure of local content. For example, PHP scripts may be served instead of interpreted. Users are recommended to upgrade to version 2.4.62, which fixes this issue. | |||||
| CVE-2023-43622 | 1 Apache | 1 Http Server | 2025-02-13 | N/A | 7.5 HIGH |
| An attacker, opening a HTTP/2 connection with an initial window size of 0, was able to block handling of that connection indefinitely in Apache HTTP Server. This could be used to exhaust worker resources in the server, similar to the well known "slow loris" attack pattern. This has been fixed in version 2.4.58, so that such connection are terminated properly after the configured connection timeout. This issue affects Apache HTTP Server: from 2.4.55 through 2.4.57. Users are recommended to upgrade to version 2.4.58, which fixes the issue. | |||||
| CVE-2023-31122 | 2 Apache, Fedoraproject | 2 Http Server, Fedora | 2025-02-13 | N/A | 7.5 HIGH |
| Out-of-bounds Read vulnerability in mod_macro of Apache HTTP Server.This issue affects Apache HTTP Server: through 2.4.57. | |||||
| CVE-2023-25690 | 1 Apache | 1 Http Server | 2025-02-13 | N/A | 9.8 CRITICAL |
| Some mod_proxy configurations on Apache HTTP Server versions 2.4.0 through 2.4.55 allow a HTTP Request Smuggling attack. Configurations are affected when mod_proxy is enabled along with some form of RewriteRule or ProxyPassMatch in which a non-specific pattern matches some portion of the user-supplied request-target (URL) data and is then re-inserted into the proxied request-target using variable substitution. For example, something like: RewriteEngine on RewriteRule "^/here/(.*)" "http://example.com:8080/elsewhere?$1"; [P] ProxyPassReverse /here/ http://example.com:8080/ Request splitting/smuggling could result in bypass of access controls in the proxy server, proxying unintended URLs to existing origin servers, and cache poisoning. Users are recommended to update to at least version 2.4.56 of Apache HTTP Server. | |||||
| CVE-2006-20001 | 1 Apache | 1 Http Server | 2025-02-13 | N/A | 7.5 HIGH |
| A carefully crafted If: request header can cause a memory read, or write of a single zero byte, in a pool (heap) memory location beyond the header value sent. This could cause the process to crash. This issue affects Apache HTTP Server 2.4.54 and earlier. | |||||
| CVE-2019-9517 | 12 Apache, Apple, Canonical and 9 more | 25 Http Server, Traffic Server, Mac Os X and 22 more | 2025-01-14 | 7.8 HIGH | 7.5 HIGH |
| Some HTTP/2 implementations are vulnerable to unconstrained interal data buffering, potentially leading to a denial of service. The attacker opens the HTTP/2 window so the peer can send without constraint; however, they leave the TCP window closed so the peer cannot actually write (many of) the bytes on the wire. The attacker then sends a stream of requests for a large response object. Depending on how the servers queue the responses, this can consume excess memory, CPU, or both. | |||||
| CVE-2024-38476 | 2 Apache, Netapp | 2 Http Server, Clustered Data Ontap | 2024-12-02 | N/A | 9.8 CRITICAL |
| Vulnerability in core of Apache HTTP Server 2.4.59 and earlier are vulnerably to information disclosure, SSRF or local script execution via backend applications whose response headers are malicious or exploitable. Users are recommended to upgrade to version 2.4.60, which fixes this issue. | |||||
| CVE-2024-40898 | 2 Apache, Microsoft | 2 Http Server, Windows | 2024-11-21 | N/A | 7.5 HIGH |
| SSRF in Apache HTTP Server on Windows with mod_rewrite in server/vhost context, allows to potentially leak NTML hashes to a malicious server via SSRF and malicious requests. Users are recommended to upgrade to version 2.4.62 which fixes this issue. | |||||
| CVE-2024-27316 | 3 Apache, Fedoraproject, Netapp | 3 Http Server, Fedora, Ontap | 2024-11-21 | N/A | 7.5 HIGH |
| HTTP/2 incoming headers exceeding the limit are temporarily buffered in nghttp2 in order to generate an informative HTTP 413 response. If a client does not stop sending headers, this leads to memory exhaustion. | |||||
| CVE-2023-45802 | 3 Apache, Debian, Fedoraproject | 3 Http Server, Debian Linux, Fedora | 2024-11-21 | 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-2022-30522 | 3 Apache, Fedoraproject, Netapp | 3 Http Server, Fedora, Clustered Data Ontap | 2024-11-21 | 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-2022-29404 | 3 Apache, Fedoraproject, Netapp | 3 Http Server, Fedora, Clustered Data Ontap | 2024-11-21 | 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-2022-28614 | 3 Apache, Fedoraproject, Netapp | 3 Http Server, Fedora, Clustered Data Ontap | 2024-11-21 | 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-2022-28330 | 2 Apache, Microsoft | 2 Http Server, Windows | 2024-11-21 | 5.0 MEDIUM | 5.3 MEDIUM |
| Apache HTTP Server 2.4.53 and earlier on Windows may read beyond bounds when configured to process requests with the mod_isapi module. | |||||

| 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-2022-22720 | 5 Apache, Apple, Debian and 2 more | 8 Http Server, Mac Os X, Macos and 5 more | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |
| Apache HTTP Server 2.4.52 and earlier fails to close inbound connection when errors are encountered discarding the request body, exposing the server to HTTP Request Smuggling | |||||

| 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. | |||||
