The vulnerability of the mod_session_crypto module in the Apache HTTP Server allows attackers to perform attacks like Padding Oracle.

The vulnerability of the modsessioncrypto module in the Apache HTTP Server is related to encryption algorithm errors. The modsessioncrypto module encrypts its data/cookies using configured encryption algorithms with CBC or ECB modes AES256-CBC by default. Therefore, there is no optional or built-...

USN-3370-2: Apache HTTP Server vulnerability

USN-3370-1 fixed a vulnerability in Apache HTTP Server. This update provides the corresponding update for Ubuntu 12.04 ESM. Original advisory details: Robert Święcki discovered that the Apache HTTP Server modauthdigest module incorrectly cleared values when processing certain requests. A remote...

Ubuntu 14.04 LTS / 16.04 LTS : Apache HTTP Server vulnerability (USN-3370-1)

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-3370-1 advisory. Robert wicki discovered that the Apache HTTP Server modauthdigest module incorrectly cleared values when processing certain requests. A remote attacke...

Code injection

In Apache HTTP Server versions 2.4.0 to 2.4.23, modsessioncrypto 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...

Input validation

In Apache HTTP Server versions 2.4.0 to 2.4.23, malicious input to modauthdigest can cause the server to crash, and each instance continues to crash even for subsequently valid requests...

Design/Logic Flaw

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-en...

CVE-2016-8743

The CVE-2016-8743 issue affects Apache HTTP Server. It concerns how whitespace is accepted in requests and sent in response lines and headers in all releases before 2.2.32 and 2.4.25. The root problem is liberal whitespace handling, which can enable request smuggling, response splitting, and cach...

CVE-2016-0736

Apache HTTP Server versions 2.4.0 to 2.4.23 are vulnerable via the mod_session_crypto module. The component is susceptible to padding oracle attacks , particularly when using CBC mode of operation, because it lacks selectable or built-in authenticated encryption while encrypting data and cookies....
