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-2017-7659 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-2017-9798 3 Apache, Debian, Redhat 8 Http Server, Debian Linux, Enterprise Linux and 5 more 2025-04-20 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-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-2017-3167 6 Apache, Apple, Debian and 3 more 17 Http Server, Mac Os X, Debian Linux and 14 more 2025-04-20 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-2014-0231 2 Apache, Redhat 5 Http Server, Enterprise Linux, Jboss Enterprise Application Platform and 2 more 2025-04-12 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-2013-6438 4 Apache, Canonical, Oracle and 1 more 6 Http Server, Ubuntu Linux, Http Server and 3 more 2025-04-12 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-2015-3185 4 Apache, Apple, Canonical and 1 more 8 Http Server, Mac Os X, Mac Os X Server and 5 more 2025-04-12 N/A
The ap_some_auth_required function in server/request.c in the Apache HTTP Server 2.4.x before 2.4.14 does not consider that a Require directive may be associated with an authorization setting rather than an authentication setting, which allows remote attackers to bypass intended access restrictions in opportunistic circumstances by leveraging the presence of a module that relies on the 2.2 API behavior.
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-2014-0226 4 Apache, Debian, Oracle and 1 more 9 Http Server, Debian Linux, Enterprise Manager Ops Center and 6 more 2025-04-12 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-2015-3183 2 Apache, Redhat 5 Http Server, Enterprise Linux, Jboss Enterprise Application Platform and 2 more 2025-04-12 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-2016-5387 8 Apache, Canonical, Debian and 5 more 22 Http Server, Ubuntu Linux, Debian Linux and 19 more 2025-04-12 8.1 High
The Apache HTTP Server through 2.4.23 follows RFC 3875 section 4.1.18 and therefore does not protect applications from the presence of untrusted client data in the HTTP_PROXY environment variable, which might allow remote attackers to redirect an application's outbound HTTP traffic to an arbitrary proxy server via a crafted Proxy header in an HTTP request, aka an "httpoxy" issue. NOTE: the vendor states "This mitigation has been assigned the identifier CVE-2016-5387"; in other words, this is not a CVE ID for a vulnerability.
CVE-2016-8740 2 Apache, Redhat 3 Http Server, Jboss Core Services, Rhel Software Collections 2025-04-12 N/A
The mod_http2 module in the Apache HTTP Server 2.4.17 through 2.4.23, when the Protocols configuration includes h2 or h2c, does not restrict request-header length, which allows remote attackers to cause a denial of service (memory consumption) via crafted CONTINUATION frames in an HTTP/2 request.
CVE-2016-1546 2 Apache, Redhat 2 Http Server, Rhel Software Collections 2025-04-12 N/A
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-2015-3184 3 Apache, Apple, Redhat 4 Http Server, Subversion, Xcode and 1 more 2025-04-12 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-2015-0228 5 Apache, Apple, Canonical and 2 more 6 Http Server, Mac Os X, Mac Os X Server and 3 more 2025-04-12 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-2015-0253 4 Apache, Apple, Oracle and 1 more 6 Http Server, Mac Os X, Mac Os X Server and 3 more 2025-04-12 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-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.
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-2013-5704 5 Apache, Apple, Canonical and 2 more 17 Http Server, Mac Os X, Mac Os X Server and 14 more 2025-04-12 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."
