Detailsinfo

A vulnerability, which was classified as problematic, was found in Apple Mac OS X up to 10.9.3 (Operating System). This affects some unknown processing of the component LaunchServices. The manipulation with an unknown input leads to a access control vulnerability. CWE is classifying the issue as CWE-264. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

LaunchServices in Apple OS X before 10.10 allows attackers to bypass intended sandbox restrictions via an application that specifies a crafted handler for the Content-Type field of an object.

The weakness was published 10/16/2014 by Meder Kydyraliev with Google Security Team as HT6535 as confirmed advisory (Website). The advisory is shared at support.apple.com. This vulnerability is uniquely identified as CVE-2014-4437 since 06/20/2014. An attack has to be approached locally. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1068 for this issue. The advisory points out:

The LaunchServices interface for setting content type handlers allowed sandboxed applications to specify handlers for existing content types. A compromised application could use this to bypass sandbox restrictions.

The vulnerability scanner Nessus provides a plugin with the ID 78550 (Mac OS X < 10.10 Multiple Vulnerabilities (POODLE) (Shellshock)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family MacOS X Local Security Checks.

Upgrading to version 10.10 eliminates this vulnerability. A possible mitigation has been published immediately after the disclosure of the vulnerability. The advisory contains the following remark:

The issue was addressed by restricting sandboxed applications from specifying content type handlers.

The vulnerability is also documented in the databases at X-Force (97631), Tenable (78550), SecurityFocus (BID 70627†), SecurityTracker (ID 1031063†) and Vulnerability Center (SBV-46715†).
