4Description
A vulnerability was detected in Tenda FH1201 1.2.0.14(408). This impacts the function WrlclientSet of the file /goform/WrlclientSet of the component Parameter Handler. Performing a manipulation of the argument GO results in stack-based buffer overflow. The attack is possible to be carried out remotely. The exploit is now public and may be used.
Analysis
Stack-based buffer overflow in Tenda FH1201 router (v1.2.0.14) enables remote authenticated attackers to execute arbitrary code via the WrlclientSet function. Exploitation requires only low-privilege credentials (CVSS PR:L) and has low attack complexity (AC:L), with publicly available exploit code on GitHub. …

Remediation
Within 24 hours: Inventory all Tenda FH1201 routers in production and document affected versions; confirm whether low-privilege user accounts exist on these devices. Within 7 days: Implement network segmentation to restrict administrative access to affected routers (disable WAN-side access, enforce VPN-only administration); consider disconnecting non-critical affected units pending replacement. …
