CVE-2022-28908Network attack vector

Unauthenticated command execution via ipdoamin injection

Published May 10, 2022 · Updated Aug 3, 2024

OS command injection in TOTOLINK N600R 5.3c.7159_B20190425 allows remote attackers to execute OS commands through a crafted request. The /setting/setDiagnosisCfg handler incorporates the ipdoamin value into an operating-system command without neutralizing command syntax. The network endpoint requires no authentication, and injected commands can read or modify data or interrupt the router.
