|---|---|---|---|---|---|
| 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. | |||||

| 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." | |||||

| 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. | |||||
| CVE-2016-5387 | 8 Apache, Canonical, Debian and 5 more | 21 Http Server, Ubuntu Linux, Debian Linux and 18 more | 2025-04-12 | 6.8 MEDIUM | 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-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-2013-4352 | 1 Apache | 1 Http Server | 2025-04-12 | 4.3 MEDIUM | N/A |
| The cache_invalidate function in modules/cache/cache_storage.c in the mod_cache module in the Apache HTTP Server 2.4.6, when a caching forward proxy is enabled, allows remote HTTP servers to cause a denial of service (NULL pointer dereference and daemon crash) via vectors that trigger a missing hostname value. | |||||
| 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-2015-3185 | 3 Apache, Apple, Canonical | 5 Http Server, Mac Os X, Mac Os X Server and 2 more | 2025-04-12 | 4.3 MEDIUM | 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-2014-3581 | 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-2016-4979 | 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-2016-8740 | 1 Apache | 1 Http Server | 2025-04-12 | 5.0 MEDIUM | 7.5 HIGH |
| 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-2011-1176 | 3 Apache, Debian, Mpm-itk Project | 3 Http Server, Debian Linux, Mpm-itk | 2025-04-11 | 4.3 MEDIUM | N/A |
| The configuration merger in itk.c in the Steinar H. Gunderson mpm-itk Multi-Processing Module 2.2.11-01 and 2.2.11-02 for the Apache HTTP Server does not properly handle certain configuration sections that specify NiceValue but not AssignUserID, which might allow remote attackers to gain privileges by leveraging the root uid and root gid of an mpm-itk process. | |||||
| CVE-2012-0053 | 5 Apache, Debian, Opensuse and 2 more | 12 Http Server, Debian Linux, Opensuse and 9 more | 2025-04-11 | 4.3 MEDIUM | N/A |
| protocol.c in the Apache HTTP Server 2.2.x through 2.2.21 does not properly restrict header information during construction of Bad Request (aka 400) error documents, which allows remote attackers to obtain the values of HTTPOnly cookies via vectors involving a (1) long or (2) malformed header in conjunction with crafted web script. | |||||
| CVE-2010-0408 | 1 Apache | 1 Http Server | 2025-04-11 | 5.0 MEDIUM | N/A |
| The ap_proxy_ajp_request function in mod_proxy_ajp.c in mod_proxy_ajp in the Apache HTTP Server 2.2.x before 2.2.15 does not properly handle certain situations in which a client sends no request body, which allows remote attackers to cause a denial of service (backend server outage) via a crafted request, related to use of a 500 error code instead of the appropriate 400 error code. | |||||
| CVE-2013-1896 | 4 Apache, Canonical, Opensuse and 1 more | 10 Http Server, Ubuntu Linux, Opensuse and 7 more | 2025-04-11 | 4.3 MEDIUM | N/A |
| mod_dav.c in the Apache HTTP Server before 2.2.25 does not properly determine whether DAV is enabled for a URI, which allows remote attackers to cause a denial of service (segmentation fault) via a MERGE request in which the URI is configured for handling by the mod_dav_svn module, but a certain href attribute in XML data refers to a non-DAV URI. | |||||
| CVE-2012-1181 | 1 Apache | 2 Http Server, Mod Fcgid | 2025-04-11 | 5.0 MEDIUM | N/A |
| fcgid_spawn_ctl.c in the mod_fcgid module 2.3.6 for the Apache HTTP Server does not recognize the FcgidMaxProcessesPerClass directive for a virtual host, which makes it easier for remote attackers to cause a denial of service (memory consumption) via a series of HTTP requests that triggers a process count higher than the intended limit. | |||||
| CVE-2011-4415 | 1 Apache | 1 Http Server | 2025-04-11 | 1.2 LOW | N/A |
| The ap_pregsub function in server/util.c in the Apache HTTP Server 2.0.x through 2.0.64 and 2.2.x through 2.2.21, when the mod_setenvif module is enabled, does not restrict the size of values of environment variables, which allows local users to cause a denial of service (memory consumption or NULL pointer dereference) via a .htaccess file with a crafted SetEnvIf directive, in conjunction with a crafted HTTP request header, related to (1) the "len +=" statement and (2) the apr_pcalloc function call, a different vulnerability than CVE-2011-3607. | |||||
