CVE-2022-23943 5 Apache, Debian, Fedoraproject and 2 more 8 Http Server, Debian Linux, Fedora and 5 more 2025-05-01 9.8 Critical
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.
CVE-2022-26377 4 Apache, Fedoraproject, Netapp and 1 more 6 Http Server, Fedora, Clustered Data Ontap and 3 more 2025-05-01 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.
CVE-2022-28615 4 Apache, Fedoraproject, Netapp and 1 more 6 Http Server, Fedora, Clustered Data Ontap and 3 more 2025-05-01 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-2022-30556 4 Apache, Fedoraproject, Netapp and 1 more 5 Http Server, Fedora, Clustered Data Ontap and 2 more 2025-05-01 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-2022-31813 4 Apache, Fedoraproject, Netapp and 1 more 6 Http Server, Fedora, Clustered Data Ontap and 3 more 2025-05-01 9.8 Critical
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-2023-27522 4 Apache, Debian, Redhat and 1 more 6 Http Server, Debian Linux, Enterprise Linux and 3 more 2025-05-01 7.5 High
HTTP Response Smuggling vulnerability in Apache HTTP Server via mod_proxy_uwsgi. This issue affects Apache HTTP Server: from 2.4.30 through 2.4.55. Special characters in the origin response header can truncate/split the response forwarded to the client.
CVE-2017-7659 2 Apache, Redhat 2 Http Server, Rhel Software Collections 2025-04-20 N/A
A maliciously constructed HTTP/2 request could cause mod_http2 in Apache HTTP Server 2.4.24, 2.4.25 to dereference a NULL pointer and crash the server process.
CVE-2017-7668 6 Apache, Apple, Debian and 3 more 16 Http Server, Mac Os X, Debian Linux and 13 more 2025-04-20 7.5 High
The HTTP strict parsing changes added in Apache httpd 2.2.32 and 2.4.24 introduced a bug in token list parsing, which allows ap_find_token() to search past the end of its input string. By maliciously crafting a sequence of request headers, an attacker may be able to cause a segmentation fault, or to force ap_find_token() to return an incorrect value.
CVE-1999-0236 2 Apache, Illinois 2 Http Server, Ncsa Httpd 2025-04-20 7.5 High
ScriptAlias directory in NCSA and Apache httpd allowed attackers to read CGI programs.
CVE-2017-3169 2 Apache, Redhat 5 Http Server, Enterprise Linux, Jboss Core Services and 2 more 2025-04-20 N/A
In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, mod_ssl may dereference a NULL pointer when third-party modules call ap_hook_process_connection() during an HTTP request to an HTTPS port.
CVE-2016-8743 4 Apache, Debian, Netapp and 1 more 13 Http Server, Debian Linux, Clustered Data Ontap and 10 more 2025-04-20 7.5 High
Apache HTTP Server, in all releases prior to 2.2.32 and 2.4.25, was liberal in the whitespace accepted from requests and sent in response lines and headers. Accepting these different behaviors represented a security concern when httpd participates in any chain of proxies or interacts with back-end application servers, either through mod_proxy or using conventional CGI mechanisms, and may result in request smuggling, response splitting and cache pollution.
CVE-2017-9789 1 Apache 1 Http Server 2025-04-20 N/A
When under stress, closing many connections, the HTTP/2 handling code in Apache httpd 2.4.26 would sometimes access memory after it has been freed, resulting in potentially erratic behaviour.
CVE-2016-2161 2 Apache, Redhat 4 Http Server, Enterprise Linux, Jboss Core Services and 1 more 2025-04-20 N/A
In Apache HTTP Server versions 2.4.0 to 2.4.23, malicious input to mod_auth_digest can cause the server to crash, and each instance continues to crash even for subsequently valid requests.
CVE-2017-9788 6 Apache, Apple, Debian and 3 more 18 Http Server, Mac Os X, Debian Linux and 15 more 2025-04-20 N/A
In Apache httpd before 2.2.34 and 2.4.x before 2.4.27, the value placeholder in [Proxy-]Authorization headers of type 'Digest' was not initialized or reset before or between successive key=value assignments by mod_auth_digest. Providing an initial key with no '=' assignment could reflect the stale value of uninitialized pool memory used by the prior request, leading to leakage of potentially confidential information, and a segfault in other cases resulting in denial of service.
CVE-2014-3250 3 Apache, Puppet, Redhat 3 Http Server, Puppet, Linux 2025-04-20 N/A
The default vhost configuration file in Puppet before 3.6.2 does not include the SSLCARevocationCheck directive, which might allow remote attackers to obtain sensitive information via a revoked certificate when a Puppet master runs with Apache 2.4.
CVE-2016-0736 2 Apache, Redhat 4 Http Server, Enterprise Linux, Jboss Core Services and 1 more 2025-04-20 N/A
In Apache HTTP Server versions 2.4.0 to 2.4.23, mod_session_crypto was encrypting its data/cookie using the configured ciphers with possibly either CBC or ECB modes of operation (AES256-CBC by default), hence no selectable or builtin authenticated encryption. This made it vulnerable to padding oracle attacks, particularly with CBC.
CVE-2017-7679 2 Apache, Redhat 5 Http Server, Enterprise Linux, Jboss Core Services and 2 more 2025-04-20 N/A
In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, mod_mime can read one byte past the end of a buffer when sending a malicious Content-Type response header.
CVE-2014-0098 4 Apache, Canonical, Oracle and 1 more 7 Http Server, Ubuntu Linux, Http Server and 4 more 2025-04-12 N/A
The log_cookie function in mod_log_config.c in the mod_log_config module in the Apache HTTP Server before 2.4.8 allows remote attackers to cause a denial of service (segmentation fault and daemon crash) via a crafted cookie that is not properly handled during truncation.
CVE-2014-0117 3 Apache, Apple, Redhat 4 Http Server, Mac Os X, Enterprise Linux and 1 more 2025-04-12 N/A
The mod_proxy module in the Apache HTTP Server 2.4.x before 2.4.10, when a reverse proxy is enabled, allows remote attackers to cause a denial of service (child-process crash) via a crafted HTTP Connection header.
CVE-2014-3523 3 Apache, Microsoft, Redhat 3 Http Server, Windows, Jboss Core Services 2025-04-12 N/A
Memory leak in the winnt_accept function in server/mpm/winnt/child.c in the WinNT MPM in the Apache HTTP Server 2.4.x before 2.4.10 on Windows, when the default AcceptFilter is enabled, allows remote attackers to cause a denial of service (memory consumption) via crafted requests.
