The manipulation with an unknown input leads to a information disclosure vulnerability. Using CWE to declare the problem leads to CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. Impacted is confidentiality. CVE summarizes:
The DOMParser component in Mozilla Firefox before 15.0, Thunderbird before 15.0, and SeaMonkey before 2.12 loads subresources during parsing of text/html data within an extension, which allows remote attackers to obtain sensitive information by providing crafted data to privileged extension code.
The weakness was disclosed 08/28/2012 by Vladimir Vukicevic (vsemozhetbyt) as MFSA 2012-68 as confirmed advisory (Website). The advisory is available at mozilla.org. The public release has been coordinated in cooperation with the vendor. This vulnerability is handled as CVE-2012-3975 since 07/11/2012. The attack may be launched remotely. The successful exploitation requires a simple authentication. Technical details are unknown but a private exploit is available. This vulnerability is assigned to T1592 by the MITRE ATT&CK project.
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. If the data being parsed in an extension is untrusted, it could lead to information leakage and can potentially be combined with other attacks to become exploitable.
Upgrading to version 15 eliminates this vulnerability. A possible mitigation has been published immediately after the disclosure of the vulnerability.
The vulnerability is also documented in the vulnerability database at Tenable (61741). bugzilla.mozilla.org is providing further details. The entries 6036, 6035, 6039 and 6040 are pretty similar.
