CVE-2026-93742
CriticalCVSS 9.9Summary
A vulnerability has been identified in the Totolink A3002MU router (version Hh-B20211125.1046) in the formWsc function of the /boafrm/formWsc file. Manipulation of the localPin argument leads to command injection. The attack can be launched remotely, and a public exploit is already available.
Risk Assessment
An unauthenticated remote attacker can execute arbitrary system commands on the device, gaining full control over it. This may lead to network reconfiguration, traffic interception, or using the router as a foothold for further attacks.
Recommendation
Update the Totolink A3002MU firmware to the latest version if the vendor provides one. Until a fix is available, restrict access to the administrative interface (especially /boafrm/) to trusted networks only and consider disabling remote management.
