1 CVE-2017-9798 416 2017-09-18 2017-12-07
5.0
None Remote Low Not required Partial None None
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.
2 CVE-2017-9789 416 2017-07-13 2017-11-13
5.0
None Remote Low Not required None None Partial
When under stress, closing many connections, the HTTP/2 handling code in Apache httpd 2.4.26 would sometimes access memory after it has been freed, resulting in potentially erratic behaviour.
3 CVE-2017-9788 20 DoS +Info 2017-07-13 2017-12-08
6.4
None Remote Low Not required Partial None Partial
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.
4 CVE-2017-7679 119 Overflow 2017-06-19 2017-12-01
7.5
None Remote Low Not required Partial Partial Partial
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.
5 CVE-2017-7668 20 2017-06-19 2017-12-01
7.5
None Remote Low Not required Partial Partial Partial
The HTTP strict parsing changes added in Apache httpd 2.2.32 and 2.4.24 introduced a bug in token list parsing, which allows ap_find_token() to search past the end of its input string. By maliciously crafting a sequence of request headers, an attacker may be able to cause a segmentation fault, or to force ap_find_token() to return an incorrect value.
6 CVE-2017-7659 476 2017-07-26 2017-11-13
5.0
None Remote Low Not required None None Partial
A maliciously constructed HTTP/2 request could cause mod_http2 2.4.24, 2.4.25 to dereference a NULL pointer and crash the server process.
7 CVE-2017-3169 476 2017-06-19 2017-12-01
7.5
None Remote Low Not required Partial Partial Partial
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.
8 CVE-2017-3167 287 Bypass 2017-06-19 2017-12-01
7.5
None Remote Low Not required Partial Partial Partial
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.
9 CVE-2016-8743 19 Http R.Spl. 2017-07-27 2017-11-13
5.0
None Remote Low Not required None Partial None
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.
10 CVE-2016-2161 20 2017-07-27 2017-11-13
5.0
None Remote Low Not required None None Partial
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.
11 CVE-2016-0736 310 2017-07-27 2017-11-13
5.0
None Remote Low Not required Partial None None
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.
