Incorrect access control in the clearDiagnosisLog function of TOTOLINK T6 4.1.5cu.748_B20211015 allows unauthenticated attackers to erase diagnosis logs via sending a crafted POST request to /cgi-bin/cstecgi.cgi.
AnalysisAI
Unauthenticated log erasure in the TOTOLINK T6 router (firmware 4.1.5cu.748_B20211015) lets remote attackers delete diagnosis logs by sending a crafted POST request to the clearDiagnosisLog handler at /cgi-bin/cstecgi.cgi. The endpoint enforces no authentication, so any attacker with network reach to the web management interface can wipe diagnostic records. …
