Detailsinfo

A vulnerability classified as critical was found in Phoenix Contact TC ROUTER 3002T-3G, TC ROUTER 2002T-3G, TC ROUTER 3002T-4G, TC ROUTER 3002T-4G GL, TC ROUTER 5004T-5G EU, TC ROUTER 3002T-4G VZW, TC ROUTER 3002T-4G ATT, TC ROUTER 2002T-4G, CLOUD CLIENT 1101T-TX, TX, TC CLOUD CLIENT 1002-4G ATT and TC CLOUD CLIENT 1002-TX. Affected by this vulnerability is an unknown code. The manipulation with an unknown input leads to a code injection vulnerability. The CWE definition for the vulnerability is CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

An unauthenticated remote attacker can trick a high privileged user into uploading a malicious payload via the config-upload endpoint, leading to code injection as root. This results in a total loss of confidentiality, availability and integrity due to improper control of code generation ('Code Injection’).

The weakness was released by D. Blagojevic, S. Dietz, F. Koroknai and T. Weber as VDE-2025-073. The advisory is shared at certvde.com. This vulnerability is known as CVE-2025-41717 since 04/16/2025. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. It demands that the victim is doing some kind of user interaction.
