Remediation
Recommended actions to resolve this vulnerability, in priority order.
- Compensating control
Since the attack can be launched remotely and involves manipulation of the enable/level/module arguments to trigger a stack-based buffer overflow in Tenda W15E setDebugCfg (formSetDebugCfg), restrict remote access to the vulnerable endpoint/interface so only trusted clients can reach the device (e.g., via firewall/ACL).
- Compensating control
Block or filter requests targeting /goform/setDebugCfg on Tenda W15E from untrusted networks/clients to prevent exploitation of the stack-based overflow (argument enable/level/module).
