Detailsinfo

A vulnerability was found in Apple MacOS X up to 10.10.2 (Operating System). It has been rated as problematic. This issue affects an unknown function of the component Security Code Signing. The manipulation with an unknown input leads to a cryptographic issue vulnerability. Using CWE to declare the problem leads to CWE-310. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

The Code Signing implementation in Apple OS X before 10.10.3 does not properly validate signatures, which allows local users to bypass intended access restrictions via a crafted bundle, a different vulnerability than CVE-2015-1146.

The weakness was presented 04/08/2015 by Ole Andre Vadla Ravnas (lokihardt@ASRT) with Google Project Zero as HT204659 as confirmed advisory (Website). The advisory is shared at support.apple.com. The identification of this vulnerability is CVE-2015-1145 since 01/16/2015. An attack has to be approached locally. No form of authentication is needed for a successful exploitation. Technical details are unknown but a public exploit is available. MITRE ATT&CK project uses the attack technique T1600 for this issue.

A public exploit has been developed in Ruby. The exploit is available at securityfocus.com. It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 82699 (Mac OS X 10.10.x < 10.10.3 Multiple Vulnerabilities (FREAK)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family MacOS X Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 123515 (Apple Mac OS X v10.10.3 and Security Update 2015-004 Not Installed (APPLE-SA-2015-04-08-2)).

Upgrading to version 10.10.3 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 Tenable (82699), SecurityFocus (BID 73982†), SecurityTracker (ID 1032048†) and Vulnerability Center (SBV-49481†). See VDB-69184, VDB-74699, VDB-74700 and VDB-74701 for similar entries. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
