Siemens SCALANCE WAB762-1 prior 3.0.0 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.

Affected by this issue is an unknown function. The manipulation with an unknown input leads to a resource consumption vulnerability. Using CWE to declare the problem leads to 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. Impacted is availability. CVE summarizes:

A vulnerability has been identified in SCALANCE WAB762-1 (6GK5762-1AJ00-6AA0) (All versions < V3.0.0), SCALANCE WAM763-1 (6GK5763-1AL00-7DA0) (All versions < V3.0.0), SCALANCE WAM763-1 (ME) (6GK5763-1AL00-7DC0) (All versions < V3.0.0), SCALANCE WAM763-1 (US) (6GK5763-1AL00-7DB0) (All versions < V3.0.0), SCALANCE WAM766-1 (6GK5766-1GE00-7DA0) (All versions < V3.0.0), SCALANCE WAM766-1 (ME) (6GK5766-1GE00-7DC0) (All versions < V3.0.0), SCALANCE WAM766-1 (US) (6GK5766-1GE00-7DB0) (All versions < V3.0.0), SCALANCE WAM766-1 EEC (6GK5766-1GE00-7TA0) (All versions < V3.0.0), SCALANCE WAM766-1 EEC (ME) (6GK5766-1GE00-7TC0) (All versions < V3.0.0), SCALANCE WAM766-1 EEC (US) (6GK5766-1GE00-7TB0) (All versions < V3.0.0), SCALANCE WUB762-1 (6GK5762-1AJ00-1AA0) (All versions < V3.0.0), SCALANCE WUB762-1 iFeatures (6GK5762-1AJ00-2AA0) (All versions < V3.0.0), SCALANCE WUM763-1 (6GK5763-1AL00-3AA0) (All versions < V3.0.0), SCALANCE WUM763-1 (6GK5763-1AL00-3DA0) (All versions < V3.0.0), SCALANCE WUM763-1 (US) (6GK5763-1AL00-3AB0) (All versions < V3.0.0), SCALANCE WUM763-1 (US) (6GK5763-1AL00-3DB0) (All versions < V3.0.0), SCALANCE WUM766-1 (6GK5766-1GE00-3DA0) (All versions < V3.0.0), SCALANCE WUM766-1 (ME) (6GK5766-1GE00-3DC0) (All versions < V3.0.0), SCALANCE WUM766-1 (USA) (6GK5766-1GE00-3DB0) (All versions < V3.0.0). The integrated ICMP service of the network stack of affected devices can be forced to exhaust its available memory resources when receiving specially crafted messages targeting IP fragment re-assembly. This could allow an unauthenticated remote attacker to cause a temporary denial of service condition of the ICMP service, other communication services are not affected. Affected devices will resume normal operation after the attack terminates.
