Descriptions

An unauthenticated remote attacker can perform a remote code execution due to an origin validation error. The access is limited to the service user.

Un atacante remoto no autenticado puede realizar una ejecución remota de código debido a un error de validación de origen. El acceso está limitado al usuario del servicio.

This vulnerability allows network-adjacent attackers to bypass firewall rules and access another interface on affected installations of Phoenix Contact CHARX SEC-3100 devices. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the configuration of firewall rules. The issue results from the use of rules that filter inbound traffic on the basis of the source port. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of root.
