OpenSSL up to 0.9.8u/1.0.0h CMS/PKCS#7 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 was found in OpenSSL up to 0.9.8u/1.0.0h (Network Encryption Software). It has been classified as critical. This affects an unknown code block of the component CMS/PKCS#7. 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 summary by CVE is:

The implementation of Cryptographic Message Syntax (CMS) and PKCS #7 in OpenSSL before 0.9.8u and 1.x before 1.0.0h does not properly restrict certain oracle behavior, which makes it easier for context-dependent attackers to decrypt data via a Million Message Attack (MMA) adaptive chosen ciphertext attack.

The weakness was released 03/12/2012 (Website). The advisory is shared at openssl.org. This vulnerability is uniquely identified as CVE-2012-0884 since 01/19/2012. The exploitability is told to be difficult. It is possible to initiate the attack remotely. The requirement for exploitation is a authentication. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1600 for this issue.

The vulnerability scanner Nessus provides a plugin with the ID 69669 (Amazon Linux AMI : openssl (ALAS-2012-62)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Amazon Linux Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 185004 (HP-UX Running OpenSSL Remote Denial of Service Vulnerability (HPSBUX02782)).

Upgrading to version 0.9.8u or 1.0.0h 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 (73916), Tenable (69669), SecurityFocus (BID 52428†), OSVDB (80039†) and Secunia (SA46958†). Entries connected to this vulnerability are available at VDB-4822, VDB-60637 and VDB-60334. If you want to get the best quality for vulnerability data then you always have to consider VulDB.
