CVE-2016-8743 |
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.

V3.1: 7.5 HIGH V2.0: 5.0 MEDIUM |
CVE-2016-2161 |
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. Published: July 27, 2017; 5:29:00 PM -0400 |
V3.0: 7.5 HIGH V2.0: 5.0 MEDIUM |
CVE-2016-0736 |
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. Published: July 27, 2017; 5:29:00 PM -0400 |
V3.0: 7.5 HIGH V2.0: 5.0 MEDIUM |
CVE-2017-9788 |
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.

V3.0: 9.1 CRITICAL V2.0: 6.4 MEDIUM |
CVE-2017-7679 |
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. Published: June 19, 2017; 9:29:00 PM -0400 |
V3.0: 9.8 CRITICAL V2.0: 7.5 HIGH |
CVE-2017-3169 |
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. Published: June 19, 2017; 9:29:00 PM -0400 |
V3.0: 9.8 CRITICAL V2.0: 7.5 HIGH |
CVE-2017-3167 |
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. Published: June 19, 2017; 9:29:00 PM -0400 |
V3.1: 9.8 CRITICAL V2.0: 7.5 HIGH |
CVE-2016-8740 |
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. Published: December 05, 2016; 2:59:00 PM -0500 |
V3.0: 7.5 HIGH V2.0: 5.0 MEDIUM |
CVE-2016-5387 |
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. Published: July 18, 2016; 10:00:19 PM -0400 |
V3.1: 8.1 HIGH V2.0: 6.8 MEDIUM |
CVE-2016-4979 |
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.
