A low privileged remote attacker can use the ssh feature to execute commands directly after login. The process stays open and uses resources which leads to a reduced performance of the management functions. Switching functionality is not affected.

Multiple vulnerabilities have been identified in the FL SWITCH 2xxx firmware prior to version 3.50. Two of these (CVE-2025-41692 and CVE-2025-41696) enable an attacker to access the device's file system. Two other vulnerabilities (CVE-2025-41693 and CVE-2025-41694) are related to Denial of Service (DoS) attacks, which partly limit the device's functionality. Another vulnerability (CVE-2025-41697) allows an unauthenticated physical attacker to access a login shell via an undocumented UART port. Furthermore, there are multiple vulnerabilities relating to reflected cross-site scripting in the web-based management of the device. All vulnerabilities have been resolved in firmware version 3.50.

Ein Angreifer kann mehrere Schwachstellen in Phoenix Contact FL SWITCH ausnutzen, um Informationen offenzulegen, um einen Cross-Site Scripting Angriff durchzuführen, um einen Denial of Service Angriff durchzuführen, und um Sicherheitsvorkehrungen zu umgehen.
