TP-link TL-WA855RE Missing Authentication for Critical Function Vulnerability — TP-link TL-WA855RE contains a missing authentication for critical function vulnerability. This vulnerability could allow an unauthenticated attacker (on the same network) to submit a TDDP_RESET POST request for a factory reset and reboot. The attacker can then obtain incorrect access control by setting a new administrative password. The impacted products could be end-of-life (EoL) and/or end-of-service (EoS). Users should discontinue product utilization.

🤖 AI Executive Summary

TP-Link TL-WA855RE wireless extender lacks authentication for critical functions, allowing unauthenticated attackers on the same network to perform factory resets and set new admin passwords. This critical vulnerability affects end-of-life products and poses significant risk to network security in affected organizations.
