A vulnerability, which was classified as problematic, was found in Mozilla Firefox up to 34.0.5 (Web Browser). This affects an unknown functionality of the component Proxy Authenticate Response Handler. The manipulation with an unknown input leads to a session fixiation vulnerability. CWE is classifying the issue as CWE-384. Authenticating a user, or otherwise establishing a new user session, without invalidating any existing session identifier gives an attacker the opportunity to steal authenticated sessions. This is going to have an impact on confidentiality, and integrity.

The weakness was released 01/13/2015 by Xiaofeng Zheng as MFSA2015-04 as confirmed advisory (Website). The advisory is shared at mozilla.org. The public release was coordinated with Mozilla. This vulnerability is uniquely identified as CVE-2014-8639 since 11/06/2014. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. It demands that the victim is doing some kind of user interaction. Neither technical details nor an exploit are publicly available. The advisory points out:

Security researcher Xiaofeng Zheng of the Blue Lotus Team at Tsinghua University reported reported that a Web Proxy returning a 407 Proxy Authentication response with a Set-Cookie header could inject cookies into the originally requested domain. This could be used for session-fixation attacks. This attack only allows cookies to be written but does not allow them to be read.

The vulnerability scanner Nessus provides a plugin with the ID 80524 (Mozilla Thunderbird < 31.4 Multiple Vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Windows. The commercial vulnerability scanner Qualys is able to test this issue with plugin 167588 (OpenSuSE Security Update for seamonkey (openSUSE-SU-2015:0192-1)). The advisory illustrates:

In general this flaw cannot be exploited through email in the Thunderbird product, but is potentially a risk in browser or browser-like contexts.

Upgrading to version 35 eliminates this vulnerability. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (99959), Tenable (80524), SecurityFocus (BID 72046†), Secunia (SA62237†) and SecurityTracker (ID 1031533†).
