Technical details

This vulnerability is classified as an OS Command Injection (CWE-78) within the init-script responsible for user-applications in Phoenix Contact CHARX SEC-3xxx firmware. The root cause is the improper neutralization of special elements within the script, which allows a local attacker with low-level privileges to inject and execute arbitrary commands with root authority. The attack requires local access to the device's shell or environment. Successful exploitation leads to a complete compromise of confidentiality, integrity, and availability. The issue is resolved in firmware version 1.9.1 and later.
