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-2014-3581 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-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-2015-3184 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-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-2014-0118 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-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-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-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-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-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-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-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-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-2010-1623 1 Apache 2 Apr-util, Http Server 2025-04-11 5.0 MEDIUM N/A
Memory leak in the apr_brigade_split_line function in buckets/apr_brigade.c in the Apache Portable Runtime Utility library (aka APR-util) before 1.3.10, as used in the mod_reqtimeout module in the Apache HTTP Server and other software, allows remote attackers to cause a denial of service (memory consumption) via unspecified vectors related to the destruction of an APR bucket.
CVE-2012-4557 1 Apache 1 Http Server 2025-04-11 5.0 MEDIUM N/A
The mod_proxy_ajp module in the Apache HTTP Server 2.2.12 through 2.2.21 places a worker node into an error state upon detection of a long request-processing time, which allows remote attackers to cause a denial of service (worker consumption) via an expensive request.
CVE-2013-5697 2 Apache, Simone Tellini 2 Http Server, Mod Accounting 2025-04-11 7.5 HIGH N/A
SQL injection vulnerability in mod_accounting.c in the mod_accounting module 0.5 and earlier for Apache allows remote attackers to execute arbitrary SQL commands via a Host header.
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-2010-0010 1 Apache 1 Http Server 2025-04-11 6.8 MEDIUM N/A
Integer overflow in the ap_proxy_send_fb function in proxy/proxy_util.c in mod_proxy in the Apache HTTP Server before 1.3.42 on 64-bit platforms allows remote origin servers to cause a denial of service (daemon crash) or possibly execute arbitrary code via a large chunk size that triggers a heap-based buffer overflow.
CVE-2007-6750 1 Apache 1 Http Server 2025-04-11 5.0 MEDIUM N/A
The Apache HTTP Server 1.x and 2.x allows remote attackers to cause a denial of service (daemon outage) via partial HTTP requests, as demonstrated by Slowloris, related to the lack of the mod_reqtimeout module in versions before 2.2.15.
