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, which was classified as critical, was found in OpenSSL. Affected is an unknown function of the component RSA Handler. Executing a manipulation can lead to cryptographic issue. This vulnerability appears as CVE-2015-0204. The attack may be performed from remote. There is no available exploit. You should upgrade the affected component.

Detailsinfo

A vulnerability classified as critical was found in OpenSSL (Network Encryption Software). This vulnerability affects some unknown functionality of the component RSA Handler. The manipulation with an unknown input leads to a cryptographic issue vulnerability. The CWE definition for the vulnerability is CWE-310. As an impact it is known to affect confidentiality, integrity, and availability.

The weakness was presented 01/08/2015 by Karthikeyan Bhargavan with Prosecco as secadv_20150108.txt as confirmed advisory (Website). The advisory is available at openssl.org. The public release was coordinated in cooperation with the vendor. This vulnerability was named CVE-2015-0204 since 11/18/2014. The exploitation appears to be difficult. Local access is required to approach this attack. No form of authentication is required for a successful exploitation. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1600 by the MITRE ATT&CK project. The advisory points out:

An OpenSSL client will accept the use of an RSA temporary key in a non-export RSA key exchange ciphersuite. A server could present a weak temporary key and downgrade the security of the session.

The vulnerability was handled as a non-public zero-day exploit for at least 78 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 82820 (Oracle Java SE Multiple Vulnerabilities (April 2015 CPU) (FREAK)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Windows and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 185099 (HP-UX Running OpenSSL Multiple Vulnerabilities (HPSBUX03244)).

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:

The fix was developed by Stephen Henson of the OpenSSL core team.

The vulnerability is also documented in the databases at X-Force (99707), Tenable (82820), SecurityFocus (BID 71936†) and SecurityTracker (ID 1031513†). See VDB-68514, VDB-68515, VDB-68516 and VDB-68517 for similar entries. Once again VulDB remains the best source for vulnerability data.
