CVE-2003-0542 2 Apache, Redhat 5 Http Server, Enterprise Linux, Linux and 2 more 2025-04-03 N/A
Multiple stack-based buffer overflows in (1) mod_alias and (2) mod_rewrite for Apache before 1.3.29 allow attackers to create configuration files to cause a denial of service (crash) or execute arbitrary code via a regular expression with more than 9 captures.
CVE-2003-0189 2 Apache, Redhat 2 Http Server, Linux 2025-04-03 N/A
The authentication module for Apache 2.0.40 through 2.0.45 on Unix does not properly handle threads safely when using the crypt_r or crypt functions, which allows remote attackers to cause a denial of service (failed Basic authentication with valid usernames and passwords) when a threaded MPM is used.
CVE-2005-2970 4 Apache, Canonical, Fedoraproject and 1 more 7 Http Server, Ubuntu Linux, Fedora Core and 4 more 2025-04-03 N/A
Memory leak in the worker MPM (worker.c) for Apache 2, in certain circumstances, allows remote attackers to cause a denial of service (memory consumption) via aborted connections, which prevents the memory for the transaction pool from being reused for other connections.
CVE-2003-0134 1 Apache 1 Http Server 2025-04-03 N/A
Unknown vulnerability in filestat.c for Apache running on OS2, versions 2.0 through 2.0.45, allows unknown attackers to cause a denial of service via requests related to device names.
CVE-2005-1268 3 Apache, Debian, Redhat 6 Http Server, Debian Linux, Enterprise Linux and 3 more 2025-04-03 N/A
Off-by-one error in the mod_ssl Certificate Revocation List (CRL) verification callback in Apache, when configured to use a CRL, allows remote attackers to cause a denial of service (child process crash) via a CRL that causes a buffer overflow of one null byte.
CVE-2000-0913 1 Apache 1 Http Server 2025-04-03 N/A
mod_rewrite in Apache 1.3.12 and earlier allows remote attackers to read arbitrary files if a RewriteRule directive is expanded to include a filename whose name contains a regular expression.
CVE-2001-0731 2 Apache, Redhat 3 Http Server, Linux, Secure Web Server 2025-04-03 N/A
Apache 1.3.20 with Multiviews enabled allows remote attackers to view directory contents and bypass the index page via a URL containing the "M=D" query string.
CVE-2004-0263 2 Apache, Ibm 2 Http Server, Http Server 2025-04-03 N/A
PHP 4.3.4 and earlier in Apache 1.x and 2.x (mod_php) can leak global variables between virtual hosts that are handled by the same Apache child process but have different settings, which could allow remote attackers to obtain sensitive information.
CVE-2024-38474 3 Apache, Netapp, Redhat 9 Http Server, Clustered Data Ontap, Enterprise Linux and 6 more 2025-03-25 8.1 High
Substitution encoding issue in mod_rewrite in Apache HTTP Server 2.4.59 and earlier allows attacker to execute scripts in directories permitted by the configuration but not directly reachable by any URL or source disclosure of scripts meant to only to be executed as CGI. Users are recommended to upgrade to version 2.4.60, which fixes this issue. Some RewriteRules that capture and substitute unsafely will now fail unless rewrite flag "UnsafeAllow3F" is specified.
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-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-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-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-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
