Siemens RUGGEDCOM ROS RMC8388 up to 5.5.x HTTP Request Slowloris resource consumption

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 Siemens RUGGEDCOM ROS RMC8388, RUGGEDCOM ROS RS416Pv2, RUGGEDCOM ROS RS416v2, RUGGEDCOM ROS RS900, RUGGEDCOM ROS RS900G, RUGGEDCOM ROS RSG2100, RUGGEDCOM ROS RSG2288, RUGGEDCOM ROS RSG2300, RUGGEDCOM ROS RSG2300P, RUGGEDCOM ROS RSG2488, RUGGEDCOM ROS RSG907R, RUGGEDCOM ROS RSG908C, RUGGEDCOM ROS RSG909R, RUGGEDCOM ROS RSG910C, RUGGEDCOM ROS RSG920P, RUGGEDCOM ROS RSL910, RUGGEDCOM ROS RST2228, RUGGEDCOM ROS RST2228P, RUGGEDCOM ROS RST916C and RUGGEDCOM ROS RST916P up to 5.5.x. It has been classified as problematic. This affects an unknown part of the component HTTP Request Handler. The manipulation with an unknown input leads to a resource consumption vulnerability. CWE is classifying the issue as CWE-400. The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources. This is going to have an impact on availability. The summary by CVE is:

A vulnerability has been identified in RUGGEDCOM ROS RMC8388 (All versions < V5.6.0), RUGGEDCOM ROS RS416Pv2 (All versions < V5.6.0), RUGGEDCOM ROS RS416v2 (All versions < V5.6.0), RUGGEDCOM ROS RS900 (32M) (All versions < V5.6.0), RUGGEDCOM ROS RS900G (32M) (All versions < V5.6.0), RUGGEDCOM ROS RSG2100 (32M) (All versions < V5.6.0), RUGGEDCOM ROS RSG2288 (All versions < V5.6.0), RUGGEDCOM ROS RSG2300 (All versions < V5.6.0), RUGGEDCOM ROS RSG2300P (All versions < V5.6.0), RUGGEDCOM ROS RSG2488 (All versions < V5.6.0), RUGGEDCOM ROS RSG907R (All versions < V5.6.0), RUGGEDCOM ROS RSG908C (All versions < V5.6.0), RUGGEDCOM ROS RSG909R (All versions < V5.6.0), RUGGEDCOM ROS RSG910C (All versions < V5.6.0), RUGGEDCOM ROS RSG920P (All versions < V5.6.0), RUGGEDCOM ROS RSL910 (All versions < v5.6.0), RUGGEDCOM ROS RST2228 (All versions < v5.6.0), RUGGEDCOM ROS RST2228P (All versions < V5.6.0), RUGGEDCOM ROS RST916C (All versions < v5.6.0), RUGGEDCOM ROS RST916P (All versions < v5.6.0). Affected devices improperly handle partial HTTP requests which makes them vulnerable to slowloris attacks. This could allow a remote attacker to create a denial of service condition that persists until the attack ends.

The weakness was published 09/13/2022 as ssa-459643. The advisory is shared at cert-portal.siemens.com. This vulnerability is uniquely identified as CVE-2022-39158 since 09/01/2022. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1499 for this issue.

Upgrading to version 5.6.0 eliminates this vulnerability.
