Detailsinfo

A vulnerability was found in Apple Mac OS X 10.8.5/10.9.2 (Operating System). It has been rated as critical. Affected by this issue is some unknown processing of the component SSL Session Handler. The manipulation with an unknown input leads to a improper authentication vulnerability (Triple Handshake). Using CWE to declare the problem leads to CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Secure Transport in Apple iOS before 7.1.1, Apple OS X 10.8.x and 10.9.x through 10.9.2, and Apple TV before 6.1.1 does not ensure that a server's X.509 certificate is the same during renegotiation as it was before renegotiation, which allows man-in-the-middle attackers to obtain sensitive information or modify TLS session data via a "triple handshake attack."

The weakness was published 04/22/2014 by Antoine Delignat-Lavaud, Karthikeyan Bhargavan and Alfredo Pironti with Prosecco as HT6207 as confirmed advisory (Website). The advisory is shared for download at support.apple.com. The public release has been coordinated with the vendor. This vulnerability is handled as CVE-2014-1295 since 01/08/2014. The exploitation is known to be difficult. The attack may be launched remotely. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 05/11/2026). This vulnerability has a historic impact due to its background and reception. The advisory points out:

(...) it was possible for an attacker to establish two connections which had the same encryption keys and handshake, insert the attacker's data in one connection, and renegotiate so that the connections may be forwarded to each other.

The vulnerability scanner Nessus provides a plugin with the ID 73648 (Mac OS X Multiple Vulnerabilities (Security Update 2014-002)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family MacOS X Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 122028 (Apple Mac OS X Security Update 2014-002 Not Installed (HT6207)).

Applying the patch Security Update 2014-002 is able to eliminate this problem. The bugfix is ready for download at support.apple.com. A possible mitigation has been published immediately after the disclosure of the vulnerability. The advisory contains the following remark:

To prevent attacks based on this scenario, Secure Transport was changed so that, by default, a renegotiation must present the same server certificate as was presented in the original connection. This issue does not affect Mac OS X 10.7 systems and earlier.

The vulnerability is also documented in the databases at X-Force (92703), Tenable (73648), SecurityFocus (BID 67025†), Secunia (SA58081†) and SecurityTracker (ID 1030133†).
