Description

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.

Required action (CISA)

Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
