EPSS Score22.2%

EPSS (Exploit Prediction Scoring System) estimates a 22.2% chance this CVE is exploited in the wild within the next 30 days — higher than 98% of all CVEs. It complements CVSS: a high EPSS on a mid-severity CVE can still be urgent.

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