---|---|---|---|---|---|
CVE-2017-3169 | 1 Apache | 1 Http Server | 2025-04-20 | 7.5 HIGH | 9.8 CRITICAL |
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-2014-3250 | 3 Apache, Puppet, Redhat | 3 Http Server, Puppet, Linux | 2025-04-20 | 4.0 MEDIUM | 6.5 MEDIUM |
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-2017-7668 | 6 Apache, Apple, Debian and 3 more | 13 Http Server, Mac Os X, Debian Linux and 10 more | 2025-04-20 | 5.0 MEDIUM | 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 | 5.0 MEDIUM | 7.5 HIGH |
ScriptAlias directory in NCSA and Apache httpd allowed attackers to read CGI programs. | |||||
CVE-2016-8743 | 4 Apache, Debian, Netapp and 1 more | 12 Http Server, Debian Linux, Clustered Data Ontap and 9 more | 2025-04-20 | 5.0 MEDIUM | 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-2017-7679 | 1 Apache | 1 Http Server | 2025-04-20 | 7.5 HIGH | 9.8 CRITICAL |
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-2017-9798 | 2 Apache, Debian | 2 Http Server, Debian Linux | 2025-04-20 | 5.0 MEDIUM | 7.5 HIGH |
Apache httpd allows remote attackers to read secret data from process memory if the Limit directive can be set in a user's .htaccess file, or if httpd.conf has certain misconfigurations, aka Optionsbleed. This affects the Apache HTTP Server through 2.2.34 and 2.4.x through 2.4.27. The attacker sends an unauthenticated OPTIONS HTTP request when attempting to read secret data. This is a use-after-free issue and thus secret data is not always sent, and the specific data depends on many factors including configuration. Exploitation with .htaccess can be blocked with a patch to the ap_limit_section function in server/core.c. | |||||
CVE-2017-9788 | 6 Apache, Apple, Debian and 3 more | 16 Http Server, Mac Os X, Debian Linux and 13 more | 2025-04-20 | 6.4 MEDIUM | 9.1 CRITICAL |
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-2016-2161 | 1 Apache | 1 Http Server | 2025-04-20 | 5.0 MEDIUM | 7.5 HIGH |
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-2017-3167 | 6 Apache, Apple, Debian and 3 more | 15 Http Server, Mac Os X, Debian Linux and 12 more | 2025-04-20 | 7.5 HIGH | 9.8 CRITICAL |
In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, use of the ap_get_basic_auth_pw() by third-party modules outside of the authentication phase may lead to authentication requirements being bypassed. | |||||
CVE-2017-9789 | 1 Apache | 1 Http Server | 2025-04-20 | 5.0 MEDIUM | 7.5 HIGH |
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-2016-0736 | 1 Apache | 1 Http Server | 2025-04-20 | 5.0 MEDIUM | 7.5 HIGH |
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-2017-7659 | 1 Apache | 1 Http Server | 2025-04-20 | 5.0 MEDIUM | 7.5 HIGH |
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-2014-0118 | 3 Apache, Debian, Redhat | 4 Http Server, Debian Linux, Enterprise Linux and 1 more | 2025-04-12 | 4.3 MEDIUM | N/A |
The deflate_in_filter function in mod_deflate.c in the mod_deflate module in the Apache HTTP Server before 2.4.10, when request body decompression is enabled, allows remote attackers to cause a denial of service (resource consumption) via crafted request data that decompresses to a much larger size. | |||||
CVE-2014-0226 | 4 Apache, Debian, Oracle and 1 more | 7 Http Server, Debian Linux, Enterprise Manager Ops Center and 4 more | 2025-04-12 | 6.8 MEDIUM | N/A |
Race condition in the mod_status module in the Apache HTTP Server before 2.4.10 allows remote attackers to cause a denial of service (heap-based buffer overflow), or possibly obtain sensitive credential information or execute arbitrary code, via a crafted request that triggers improper scoreboard handling within the status_handler function in modules/generators/mod_status.c and the lua_ap_scoreboard_worker function in modules/lua/lua_request.c. | |||||
CVE-2014-3581 | 4 Apache, Canonical, Oracle and 1 more | 9 Http Server, Ubuntu Linux, Enterprise Manager Ops Center and 6 more | 2025-04-12 | 5.0 MEDIUM | N/A |
The cache_merge_headers_out function in modules/cache/cache_util.c in the mod_cache module in the Apache HTTP Server before 2.4.11 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via an empty HTTP Content-Type header. | |||||
CVE-2016-1546 | 1 Apache | 1 Http Server | 2025-04-12 | 4.3 MEDIUM | 5.9 MEDIUM |
The Apache HTTP Server 2.4.17 and 2.4.18, when mod_http2 is enabled, does not limit the number of simultaneous stream workers for a single HTTP/2 connection, which allows remote attackers to cause a denial of service (stream-processing outage) via modified flow-control windows. | |||||
CVE-2014-3583 | 3 Apache, Apple, Canonical | 4 Http Server, Mac Os X, Os X Server and 1 more | 2025-04-12 | 5.0 MEDIUM | N/A |
The handle_headers function in mod_proxy_fcgi.c in the mod_proxy_fcgi module in the Apache HTTP Server 2.4.10 allows remote FastCGI servers to cause a denial of service (buffer over-read and daemon crash) via long response headers. | |||||
CVE-2016-4979 | 1 Apache | 1 Http Server | 2025-04-12 | 5.0 MEDIUM | 7.5 HIGH |
The Apache HTTP Server 2.4.18 through 2.4.20, when mod_http2 and mod_ssl are enabled, does not properly recognize the "SSLVerifyClient require" directive for HTTP/2 request authorization, which allows remote attackers to bypass intended access restrictions by leveraging the ability to send multiple requests over a single connection and aborting a renegotiation. | |||||
CVE-2014-0098 | 3 Apache, Canonical, Oracle | 4 Http Server, Ubuntu Linux, Http Server and 1 more | 2025-04-12 | 5.0 MEDIUM | 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. |
