CVE-2023-44322
CVE-2023-44322
In short
The affected Siemens industrial network devices fail to properly handle certain error conditions during operation, which could allow an attacker to cause unexpected behavior or service degradation. This matters because these routers are critical infrastructure components that need to operate reliably.
Technical detail
CWE-252 (Unchecked Error Condition) allows improper error handling in RUGGEDCOM and SCALANCE industrial routers. An attacker with network access can trigger specific error conditions that bypass proper validation, potentially leading to denial of service or unexpected device behavior. Mitigation requires upgrading to version V8.0 or later (V3.0.0 for WAB762-1/WAM763-1 models).

An attacker with access to the network can use this to do disable notification of users when certain events occur.
