Siemens RuggedCom ROS up to 4.1.x CBC Padding 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 classified as critical has been found in Siemens RuggedCom ROS up to 4.1.x. This affects some unknown functionality of the component CBC Padding. 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, integrity, and availability. The summary by CVE is:

The SSL layer of the HTTPS service in Siemens RuggedCom ROS before 4.2.0 and ROX II does not properly implement CBC padding, which makes it easier for man-in-the-middle attackers to obtain cleartext data via a padding-oracle attack, a different vulnerability than CVE-2014-3566.

The weakness was shared 08/03/2015 (Website). The advisory is shared at This vulnerability is uniquely identified as CVE-2015-5537 since 07/17/2015. The exploitability is told to be difficult. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1600 for this issue.

Upgrading to version 4.2.0 eliminates this vulnerability.
