OpenSSL up to 0.9.8s/1.0.0f DTLS CBC Encryption 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 0.9.8s/1.0.0f (Network Encryption Software) and classified as problematic. Affected by this issue is some unknown processing of the component DTLS CBC Encryption. 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. CVE summarizes:

The DTLS implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f performs a MAC check only if certain padding is valid, which makes it easier for remote attackers to recover plaintext via a padding oracle attack.

The weakness was shared 01/04/2012 by Andrew with Information Security Group at Royal Holloway, University of London (Website). The advisory is available at aix.software.ibm.com. This vulnerability is handled as CVE-2011-4108 since 10/18/2011. The attack may be launched remotely. No form of authentication is required for 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 vulnerability scanner Nessus provides a plugin with the ID 75598 (openSUSE Security Update : libopenssl-devel (openSUSE-SU-2012:0083-1)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family SuSE Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 216041 (VMWare ESXi 5.0.0 Patch ESXi500-Update02 Missing (KB2033751)).

Upgrading to version 0.9.8s or 1.0.0f 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 (72128), Tenable (75598), SecurityFocus (BID 51281†), OSVDB (78186†) and Secunia (SA47426†).
