| 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-2024-38477 | 3 Apache, Netapp, Redhat | 9 Http Server, Clustered Data Ontap, Enterprise Linux and 6 more | 2025-03-18 | 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 | 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-2024-39573 | 2 Apache, Redhat | 4 Http Server, Enterprise Linux, Jboss Core Services and 1 more | 2025-02-13 | 7.5 High |
| Potential SSRF in mod_rewrite in Apache HTTP Server 2.4.59 and earlier allows an attacker to cause unsafe RewriteRules to unexpectedly setup URL's to be handled by mod_proxy. Users are recommended to upgrade to version 2.4.60, which fixes this issue. | ||||
| CVE-2024-38476 | 3 Apache, Netapp, Redhat | 9 Http Server, Clustered Data Ontap, Enterprise Linux and 6 more | 2025-02-13 | 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-2024-27316 | 4 Apache, Fedoraproject, Netapp and 1 more | 7 Http Server, Fedora, Ontap and 4 more | 2025-02-13 | 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-2023-43622 | 2 Apache, Redhat | 2 Http Server, Enterprise Linux | 2025-02-13 | 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 | 3 Apache, Fedoraproject, Redhat | 4 Http Server, Fedora, Enterprise Linux and 1 more | 2025-02-13 | 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 | 2 Apache, Redhat | 8 Http Server, Enterprise Linux, Jboss Core Services and 5 more | 2025-02-13 | 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 | 2 Apache, Redhat | 3 Http Server, Enterprise Linux, Jboss Core Services | 2025-02-13 | 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-2023-38709 | 2 Apache, Redhat | 3 Http Server, Enterprise Linux, Jboss Core Services | 2025-02-13 | 7.3 High |
| Faulty input validation in the core of Apache allows malicious or exploitable backend/content generators to split HTTP responses. This issue affects Apache HTTP Server: through 2.4.58. | ||||
| CVE-2019-9517 | 12 Apache, Apple, Canonical and 9 more | 28 Http Server, Traffic Server, Mac Os X and 25 more | 2025-01-14 | 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-2024-40898 | 3 Apache, Microsoft, Redhat | 3 Http Server, Windows, Jboss Core Services | 2024-11-21 | 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-2023-45802 | 4 Apache, Debian, Fedoraproject and 1 more | 6 Http Server, Debian Linux, Fedora and 3 more | 2024-11-21 | 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 | 4 Apache, Fedoraproject, Netapp and 1 more | 6 Http Server, Fedora, Clustered Data Ontap and 3 more | 2024-11-21 | 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 | 4 Apache, Fedoraproject, Netapp and 1 more | 5 Http Server, Fedora, Clustered Data Ontap and 2 more | 2024-11-21 | 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 | 4 Apache, Fedoraproject, Netapp and 1 more | 6 Http Server, Fedora, Clustered Data Ontap and 3 more | 2024-11-21 | 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 | 3 Apache, Microsoft, Redhat | 3 Http Server, Windows, Jboss Core Services | 2024-11-21 | 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. | ||||
| CVE-2022-22721 | 6 Apache, Apple, Debian and 3 more | 11 Http Server, Mac Os X, Macos and 8 more | 2024-11-21 | 9.1 Critical |
| 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 | 6 Apache, Apple, Debian and 3 more | 16 Http Server, Mac Os X, Macos and 13 more | 2024-11-21 | 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 | ||||
