OTRS up to 2.3.2 cryptographic issues

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.

A vulnerability was found in OTRS up to 2.3.2 (Service Management Software). It has been classified as problematic. Affected is an unknown function. The manipulation with an unknown input leads to a cryptographic issues vulnerability. CWE is classifying the issue as CWE-310. This is going to have an impact on confidentiality. CVE summarizes:

The S/MIME feature in Open Ticket Request System (OTRS) before 2.3.4 does not configure the RANDFILE and HOME environment variables for OpenSSL, which might make it easier for remote attackers to decrypt e-mail messages that had lower than intended entropy available for cryptographic operations, related to inability to write to the seeding file.

The weakness was presented 03/18/2011 (Website). The advisory is shared for download at bugs.otrs.org. This vulnerability is traded as CVE-2009-5057. The exploitability is told to be easy. It is possible to launch the attack remotely. 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.

Upgrading to version 0.5 eliminates this vulnerability.

The vulnerability is also documented in the vulnerability database at X-Force (66364). See 56872, 56871, 56870 and 56869 for similar entries.
