30th percentile - higher than 30% of all known CVEs

Summary

An authentication weakness exists in the TP-Link TDDP v2 service of TP-Link RE305 V3, which uses a fixed and derivable cryptographic key. An unauthenticated attacker on the same local network may forge protocol packets and access privileged TDDP operations, including functionality that can lead to operating-system command execution.

Risk Assessment

Successful exploitation may allow an unauthenticated attacker on the same LAN to execute arbitrary system commands with root privileges.

Recommendation

Disable or restrict access to the TDDP service, update TP-Link RE305 V3 firmware to a patched version, and segment the network to limit access to the management interface.

Original NVD description (English source)

An authentication weakness exists in the TP-Link TDDP v2 service of TP-Link RE305 V3. TDDP v2 uses a fixed and derivable cryptographic key, which may allow an unauthenticated attacker on the same local network to forge protocol packets and access privileged TDDP operations, including functionality that can lead to operating-system command execution when the TDDP service is running and accessible. Successful exploitation may allow an unauthenticated attacker on the same local area network to execute arbitrary system commands with root privileges.
