Detailsinfo

A vulnerability, which was classified as problematic, has been found in Mozilla Firefox up to 34.0.5 (Web Browser). Affected by this issue is an unknown function of the component sendBeacon Request Handler. The manipulation with an unknown input leads to a cross-site request forgery vulnerability. Using CWE to declare the problem leads to CWE-352. The web application does not, or can not, sufficiently verify whether a well-formed, valid, consistent request was intentionally provided by the user who submitted the request. Impacted is confidentiality, and integrity.

The weakness was published 01/13/2015 by Muneaki Nishimura as MFSA2015-03 as confirmed advisory (Website). The advisory is shared for download at mozilla.org. The public release has been coordinated with the vendor. This vulnerability is handled as CVE-2014-8638 since 11/06/2014. The attack may be launched remotely. No form of authentication is required for exploitation. Successful exploitation requires user interaction by the victim. Technical details are unknown but an exploit is available. The advisory points out:

Security researcher Muneaki Nishimura reported that navigator.sendBeacon() does not follow the cross-origin resource sharing (CORS) specification. This results in the request from sendBeacon() lacking an origin header in violation of the W3C Beacon specification and not being treated as a CORS request. This allows for a potential Cross-site request forgery (XSRF) attack from malicious websites.

It is declared as highly functional. The vulnerability scanner Nessus provides a plugin with the ID 80526 (CentOS 5 / 6 / 7 : firefox / xulrunner (CESA-2015:0046)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CentOS Local Security Checks. 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 because scripting is disabled, 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 (99958), Tenable (80526), SecurityFocus (BID 72047†), Secunia (SA62237†) and SecurityTracker (ID 1031533†). bugzilla.mozilla.org is providing further details.
