Detailsinfo

A vulnerability classified as critical has been found in ipTIME A2003NS-MU, N600, A604-V3, A6ns-M, V508, N704QCA, A8ns-M, A304, A9004M, N702R, A604M, A804NS-MU, N804R, A8004T, A604G-MU, A3008-MU, A2004MU and A2004NS-MU, N702E, N604E, N104E, A8004ITL, N102E, N102i, T5004, N602E, AX8004BCM and A8004T-XR, T5008, N704E, A8004BCM, AX3004ITL and A604G-skylife. This affects the function upnp_relay. The manipulation with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

A command injection vulnerability exists in the upnp_relay() function in multiple ipTIME router models because the controlURL value used to pass port-forwarding information to an upper router is passed to system() without proper validation or sanitization, allowing OS command injection.

This vulnerability is uniquely identified as CVE-2025-55423. The exploitability is told to be easy. Technical details of the vulnerability are known, but there is no available exploit. The pricing for an exploit might be around USD $0-$5k at the moment (estimation calculated on 01/27/2026). The attack technique deployed by this issue is T1202 according to MITRE ATT&CK.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
