Senserva AI Opinion for CVE-2025-9377
TP-Link Archer C7(EU) and TL-WR841N/ND(MS) routers have an OS command injection in the Parental Control page, and the hardware is end-of-life, so fixes may never fully cover the installed base. Exploitation was confirmed in September 2025; consumer-grade routers like these persist in branch and home offices long past their support window.
Do this: Find and replace these end-of-life TP-Link models; where replacement lags, block their management interfaces from any reachable network.
