CVE-2021-27692

Command Injection in Tenda G1 and G3 routers with firmware versions v15.11.0.17(9502)_CN or v15.11.0.16(9024)_CN allows remote attackers to execute arbitrary OS commands via a crafted «action/umountUSBPartition» request. This occurs because the «formSetUSBPartitionUmount» function executes the «doSystemCmd» function with untrusted input.
