Deeper analysis

A vulnerability classified as critical exists in the Totolink N200RE router running firmware 9.3.5u.6139_B20201216. It resides in the setDiagnosisCfg function within /cgi-bin/cstecgi.cgi, where improper handling of the ip argument permits OS command injection. The issue is tracked as CVE-2024-0298 with CWE-78 and carries a CVSS 3.1 base score of 7.3.

Remote unauthenticated attackers can supply a crafted ip value to the CGI endpoint and execute arbitrary operating-system commands. Successful exploitation yields limited effects on confidentiality, integrity, and availability. A working exploit has been made public, and the vendor did not respond to early disclosure notification.

The associated EPSS probability rose from a low starting value to a peak of 0.0656 on 2025-01-22 before receding to the current 0.0207, indicating that exploitation interest increased well after the initial publication. No official patches or mitigation guidance appear in the referenced sources.
