Apple Mac OS X 10.10/10.10.1 input validation

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

As an impact it is known to affect confidentiality, and integrity. The summary by CVE is:

The kernel in Apple OS X before 10.10.2 does not properly perform identitysvc validation of certain directory-service functionality, which allows local users to gain privileges or spoof directory-service responses via unspecified vectors.

The weakness was presented 01/27/2015 by Alex Radocea (PanguTeam) with CrowdStrike as HT204244 as confirmed advisory (Website). The advisory is shared at support.apple.com. This vulnerability is known as CVE-2014-8825 since 11/14/2014. An attack has to be approached locally. Required for exploitation is a single authentication. Neither technical details nor an exploit are publicly available. The advisory points out:

Issues existed in identitysvc validation of the directory service resolving process, flag handling, and error handling. This issue was addressed through improved validation.

The vulnerability scanner Nessus provides a plugin with the ID 81087 (Mac OS X 10.10.x < 10.10.2 Multiple Vulnerabilities (POODLE)), 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 123193 (Apple Mac OS X v10.10.2 and Security Update 2015-001 Not Installed (APPLE-SA-2015-01-27-4)).
