Details
A vulnerability, which was classified as problematic, has been found in Mozilla Firefox 14 (Web Browser). Affected by this issue is some unknown processing of the component HTTPMonitor Extension. The manipulation with an unknown input leads to a access control vulnerability. Using CWE to declare the problem leads to CWE-264. Impacted is confidentiality, and integrity. CVE summarizes:
The debugger in the developer-tools subsystem in Mozilla Firefox before 15.0, when remote debugging is disabled, does not properly restrict access to the remote-debugging service, which allows remote attackers to execute arbitrary code by leveraging the presence of the HTTPMonitor extension and connecting to that service through the HTTPMonitor port.
The weakness was presented 08/28/2012 by Mark Goodwin as MFSA 2012-66 as confirmed advisory (Website). The advisory is shared for download at mozilla.org. The public release was coordinated in cooperation with the vendor. This vulnerability is handled as CVE-2012-3973 since 07/11/2012. The attack may be launched remotely. Required for exploitation is a simple authentication. Technical details are unknown but a private exploit is available. The MITRE ATT&CK project declares the attack technique as T1068.
It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 61741 (FreeBSD : mozilla -- multiple vulnerabilities (2b8cad90-f289-11e1-a215-14dae9ebcf89)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family FreeBSD Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 165433 (SUSE Enterprise Linux Security Update for Mozilla Firefox (SUSE-SU-2012:1167-1)). If remote debugging is disabled, but the experimental HTTPMonitor extension has been installed and enabled, a remote user can connect to and use the remote debugging service through the port used by HTTPMonitor.
Upgrading to version 15 eliminates this vulnerability. It is possible to mitigate the problem by applying the configuration setting remote-enabled. The best possible mitigation is suggested to be upgrading to the latest version. A possible mitigation has been published immediately after the disclosure of the vulnerability.
The vulnerability is also documented in the databases at Tenable (61741), SecurityFocus (BID 55308†), OSVDB (85005†), Secunia (SA50088†) and SecurityTracker (ID 1027450†). bugzilla.mozilla.org is providing further details.
