| CVE | Vendors | Products | Updated | CVSS v2 | CVSS v3 |
|---|---|---|---|---|---|
| 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-2017-9788 | 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-2017-9798 | 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-2017-7679 | 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-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-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-2014-8109 | 4 Apache, Canonical, Fedoraproject and 1 more | 4 Http Server, Ubuntu Linux, Fedora and 1 more | 2025-04-12 | 4.3 MEDIUM | N/A |
| mod_lua.c in the mod_lua module in the Apache HTTP Server 2.3.x and 2.4.x through 2.4.10 does not support an httpd configuration in which the same Lua authorization provider is used with different arguments within different contexts, which allows remote attackers to bypass intended access restrictions in opportunistic circumstances by leveraging multiple Require directives, as demonstrated by a configuration that specifies authorization for one group to access a certain directory, and authorization for a second group to access a second directory. | |||||
| CVE-2015-0228 | 4 Apache, Apple, Canonical and 1 more | 5 Http Server, Mac Os X, Mac Os X Server and 2 more | 2025-04-12 | 5.0 MEDIUM | N/A |
| The lua_websocket_read function in lua_request.c in the mod_lua module in the Apache HTTP Server through 2.4.12 allows remote attackers to cause a denial of service (child-process crash) by sending a crafted WebSocket Ping frame after a Lua script has called the wsupgrade function. | |||||
| CVE-2015-3184 | 2 Apache, Apple | 3 Http Server, Subversion, Xcode | 2025-04-12 | 5.0 MEDIUM | N/A |
| mod_authz_svn in Apache Subversion 1.7.x before 1.7.21 and 1.8.x before 1.8.14, when using Apache httpd 2.4.x, does not properly restrict anonymous access, which allows remote anonymous users to read hidden files via the path name. | |||||
| CVE-2015-0253 | 3 Apache, Apple, Oracle | 5 Http Server, Mac Os X, Mac Os X Server and 2 more | 2025-04-12 | 5.0 MEDIUM | N/A |
| The read_request_line function in server/protocol.c in the Apache HTTP Server 2.4.12 does not initialize the protocol structure member, which allows remote attackers to cause a denial of service (NULL pointer dereference and process crash) by sending a request that lacks a method to an installation that enables the INCLUDES filter and has an ErrorDocument 400 directive specifying a local URI. | |||||
| CVE-2013-6438 | 3 Apache, Canonical, Oracle | 3 Http Server, Ubuntu Linux, Http Server | 2025-04-12 | 5.0 MEDIUM | N/A |
| The dav_xml_get_cdata function in main/util.c in the mod_dav module in the Apache HTTP Server before 2.4.8 does not properly remove whitespace characters from CDATA sections, which allows remote attackers to cause a denial of service (daemon crash) via a crafted DAV WRITE request. | |||||
| 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-2014-0231 | 1 Apache | 1 Http Server | 2025-04-12 | 5.0 MEDIUM | N/A |
| The mod_cgid module in the Apache HTTP Server before 2.4.10 does not have a timeout mechanism, which allows remote attackers to cause a denial of service (process hang) via a request to a CGI script that does not read from its stdin file descriptor. | |||||
| CVE-2015-3183 | 1 Apache | 1 Http Server | 2025-04-12 | 5.0 MEDIUM | N/A |
| The chunked transfer coding implementation in the Apache HTTP Server before 2.4.14 does not properly parse chunk headers, which allows remote attackers to conduct HTTP request smuggling attacks via a crafted request, related to mishandling of large chunk-size values and invalid chunk-extension characters in modules/http/http_filters.c. | |||||
| CVE-2013-5704 | 5 Apache, Apple, Canonical and 2 more | 16 Http Server, Mac Os X, Mac Os X Server and 13 more | 2025-04-12 | 5.0 MEDIUM | N/A |
| The mod_headers module in the Apache HTTP Server 2.2.22 allows remote attackers to bypass "RequestHeader unset" directives by placing a header in the trailer portion of data sent with chunked transfer coding. NOTE: the vendor states "this is not a security issue in httpd as such." | |||||
| CVE-2014-0117 | 2 Apache, Apple | 2 Http Server, Mac Os X | 2025-04-12 | 4.3 MEDIUM | 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-2014-0098 | 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. | |||||
| CVE-2014-3523 | 2 Apache, Microsoft | 2 Http Server, Windows | 2025-04-12 | 5.0 MEDIUM | 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. | |||||
| 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. | |||||
