CVE-2003-0987 2 Apache, Redhat 4 Http Server, Enterprise Linux, Rhel Stronghold and 1 more 2026-04-16 N/A
mod_digest for Apache before 1.3.31 does not properly verify the nonce of a client response by using a AuthNonce secret.
CVE-2002-0654 1 Apache 1 Http Server 2026-04-16 N/A
Apache 2.0 through 2.0.39 on Windows, OS2, and Netware allows remote attackers to determine the full pathname of the server via (1) a request for a .var file, which leaks the pathname in the resulting error message, or (2) via an error message that occurs when a script (child process) cannot be invoked.
CVE-2001-1342 1 Apache 1 Http Server 2026-04-16 N/A
Apache before 1.3.20 on Windows and OS/2 systems allows remote attackers to cause a denial of service (GPF) via an HTTP request for a URI that contains a large number of / (slash) or other characters, which causes certain functions to dereference a null pointer.
CVE-2004-0885 2 Apache, Redhat 6 Http Server, Enterprise Linux, Network Proxy and 3 more 2026-04-16 N/A
The mod_ssl module in Apache 2.0.35 through 2.0.52, when using the "SSLCipherSuite" directive in directory or location context, allows remote clients to bypass intended restrictions by using any cipher suite that is allowed by the virtual host configuration.
CVE-2001-1072 1 Apache 1 Http Server 2026-04-16 N/A
Apache with mod_rewrite enabled on most UNIX systems allows remote attackers to bypass RewriteRules by inserting extra / (slash) characters into the requested path, which causes the regular expression in the RewriteRule to fail.
CVE-2003-0017 1 Apache 1 Http Server 2026-04-16 N/A
Apache 2.0 before 2.0.44 on Windows platforms allows remote attackers to obtain certain files via an HTTP request that ends in certain illegal characters such as ">", which causes a different filename to be processed and served.
CVE-2002-0249 1 Apache 1 Http Server 2026-04-16 N/A
PHP for Windows, when installed on Apache 2.0.28 beta as a standalone CGI module, allows remote attackers to obtain the physical path of the php.exe via a request with malformed arguments such as /123, which leaks the pathname in the error message.
CVE-2006-3918 4 Apache, Canonical, Debian and 1 more 9 Http Server, Ubuntu Linux, Debian Linux and 6 more 2026-04-16 N/A
http_protocol.c in (1) IBM HTTP Server 6.0 before 6.0.2.13 and 6.1 before 6.1.0.1, and (2) Apache HTTP Server 1.3 before 1.3.35, 2.0 before 2.0.58, and 2.2 before 2.2.2, does not sanitize the Expect header from an HTTP request when it is reflected back in an error message, which might allow cross-site scripting (XSS) style attacks using web client components that can send arbitrary headers in requests, as demonstrated using a Flash SWF file.
CVE-2002-0240 1 Apache 1 Http Server 2026-04-16 N/A
PHP, when installed with Apache and configured to search for index.php as a default web page, allows remote attackers to obtain the full pathname of the server via the HTTP OPTIONS method, which reveals the pathname in the resulting error message.
CVE-2002-1850 1 Apache 1 Http Server 2026-04-16 7.5 High
mod_cgi in Apache 2.0.39 and 2.0.40 allows local users and possibly remote attackers to cause a denial of service (hang and memory consumption) by causing a CGI script to send a large amount of data to stderr, which results in a read/write deadlock between httpd and the CGI script.
CVE-2003-0253 2 Apache, Redhat 2 Http Server, Linux 2026-04-16 N/A
The prefork MPM in Apache 2 before 2.0.47 does not properly handle certain errors from accept, which could lead to a denial of service.
CVE-2001-0730 2 Apache, Redhat 3 Http Server, Linux, Secure Web Server 2026-04-16 N/A
split-logfile in Apache 1.3.20 allows remote attackers to overwrite arbitrary files that end in the .log extension via an HTTP request with a / (slash) in the Host: header.
CVE-2003-0542 2 Apache, Redhat 5 Http Server, Enterprise Linux, Linux and 2 more 2026-04-16 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-2025-23048 2 Apache, Apache Software Foundation 2 Http Server, Apache Http Server 2026-02-26 9.1 Critical
In some mod_ssl configurations on Apache HTTP Server 2.4.35 through to 2.4.63, an access control bypass by trusted clients is possible using TLS 1.3 session resumption. Configurations are affected when mod_ssl is configured for multiple virtual hosts, with each restricted to a different set of trusted client certificates (for example with a different SSLCACertificateFile/Path setting). In such a case, a client trusted to access one virtual host may be able to access another virtual host, if SSLStrictSNIVHostCheck is not enabled in either virtual host.
CVE-2025-58098 1 Apache 1 Http Server 2026-02-26 8.3 High
Apache HTTP Server 2.4.65 and earlier with Server Side Includes (SSI) enabled and mod_cgid (but not mod_cgi) passes the shell-escaped query string to #exec cmd="..." directives. This issue affects Apache HTTP Server before 2.4.66. Users are recommended to upgrade to version 2.4.66, which fixes the issue.
CVE-2021-41773 4 Apache, Fedoraproject, Netapp and 1 more 4 Http Server, Fedora, Cloud Backup and 1 more 2026-02-17 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-2023-25690 2 Apache, Redhat 8 Http Server, Enterprise Linux, Jboss Core Services and 5 more 2025-12-18 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-2022-28615 4 Apache, Fedoraproject, Netapp and 1 more 6 Http Server, Fedora, Clustered Data Ontap and 3 more 2025-12-18 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-2025-59775 2 Apache, Microsoft 2 Http Server, Windows 2025-12-10 7.5 High
Server-Side Request Forgery (SSRF) vulnerability  in Apache HTTP Server on Windows with AllowEncodedSlashes On and MergeSlashes Off  allows to potentially leak NTLM hashes to a malicious server via SSRF and malicious requests or content Users are recommended to upgrade to version 2.4.66, which fixes the issue.
CVE-2025-65082 1 Apache 1 Http Server 2025-12-10 6.5 Medium
Improper Neutralization of Escape, Meta, or Control Sequences vulnerability in Apache HTTP Server through environment variables set via the Apache configuration unexpectedly superseding variables calculated by the server for CGI programs. This issue affects Apache HTTP Server from 2.4.0 through 2.4.65. Users are recommended to upgrade to version 2.4.66 which fixes the issue.
