HIGHCVSS v3.1 7.2Vulnerability
CVE-2026-118238
The Tenda W18E web management server is vulnerable to OS command injection via the "diagnose" packet-capture feature due to improper validation of JSON fields. An authenticated user can inject shell metacharacters into the protocol or targetDevice fields, which are later concatenated into a tcpdump command and executed with root privileges. This vulnerability can be exploited without authentication if the device is in a factory-reset state.
