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.

Summaryinfo

A vulnerability was found in OpenSSL and classified as critical. Affected by this issue is some unknown functionality of the component Certificate Fingerprint Handler. The manipulation results in cryptographic issue. This vulnerability is known as CVE-2014-8275. It is possible to launch the attack remotely. No exploit is available. It is suggested to upgrade the affected component.

Detailsinfo

A vulnerability, which was classified as critical, was found in OpenSSL (Network Encryption Software). Affected is an unknown code of the component Certificate Fingerprint Handler. The manipulation with an unknown input leads to a cryptographic issue vulnerability. CWE is classifying the issue as CWE-310. This is going to have an impact on confidentiality, and integrity.

The weakness was published 01/08/2015 by Antti Karjalainen and Tuomo Untinen with Codenomicon CROSS Project as secadv_20150108.txt as confirmed advisory (Website). The advisory is shared for download at openssl.org. The public release has been coordinated with the vendor. This vulnerability is traded as CVE-2014-8275 since 10/12/2014. The exploitability is told to be difficult. The attack needs to be approached locally. The exploitation doesn't require any form of authentication. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1600. The advisory points out:

OpenSSL accepts several non-DER-variations of certificate signature algorithm and signature encodings. OpenSSL also does not enforce a match between the signature algorithm between the signed and unsigned portions of the certificate. By modifying the contents of the signature algorithm or the encoding of the signature, it is possible to change the certificate's fingerprint. This does not allow an attacker to forge certificates, and does not affect certificate verification or OpenSSL servers/clients in any other way. It also does not affect common revocation mechanisms. Only custom applications that rely on the uniqueness of the fingerprint (e.g. certificate blacklists) may be affected.

The vulnerability was handled as a non-public zero-day exploit for at least 38 days. During that time the estimated underground price was around $5k-$25k. 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 0.9.8zd, 1.0.0p or 1.0.1k eliminates this vulnerability. A possible mitigation has been published 4 months after the disclosure of the vulnerability. The advisory contains the following remark:

Further analysis was conducted and fixes were developed by Stephen Henson of the OpenSSL core team.

The vulnerability is also documented in the databases at X-Force (99709), Tenable (82783), SecurityFocus (BID 71935†) and SecurityTracker (ID 1031513†). Similar entries are available at VDB-68514, VDB-68515, VDB-68516 and VDB-68517. VulDB is the best source for vulnerability data and more expert information about this specific topic.
