Apple MacOS X up to 10.10.2 OpenSSL cryptographic issue

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.

Detailsinfo

A vulnerability, which was classified as critical, has been found in Apple MacOS X up to 10.10.2 (Operating System). This issue affects an unknown functionality of the component OpenSSL. 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:

OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k does not enforce certain constraints on certificate data, which allows remote attackers to defeat a fingerprint-based certificate-blacklist protection mechanism by including crafted data within a certificate's unsigned portion, related to crypto/asn1/a_verify.c, crypto/dsa/dsa_asn1.c, crypto/ecdsa/ecs_vrf.c, and crypto/x509/x_all.c.

The weakness was disclosed 04/08/2015 as HT204659 as confirmed advisory (Website). It is possible to read the advisory at support.apple.com. The identification of this vulnerability is CVE-2014-8275 since 10/12/2014. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. The technical details are unknown and an exploit is not publicly available. The attack technique deployed by this issue is T1600 according to MITRE ATT&CK. The advisory points out:

Multiple vulnerabilities existed in OpenSSL 0.9.8zc, including one that may allow an attacker to intercept connections to a server that supports export-grade ciphers. These issues were addressed by updating OpenSSL to version 0.9.8zd.

The vulnerability scanner Nessus provides a plugin with the ID 82783 (CentOS 5 : openssl (CESA-2015:0800) (FREAK)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family CentOS Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 350233 (Amazon Linux Security Advisory for openssl: ALAS-2015-469).

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 X-Force (99709), Tenable (82783), SecurityFocus (BID 71935†), SecurityTracker (ID 1032048†) and Vulnerability Center (SBV-56868†). The entries VDB-68515, VDB-68519, VDB-68520 and VDB-68521 are pretty similar. Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
