Missing authentication in TP-Link TL-WA855RE V5 TDDP_RESET allows admin takeover
CVE-2020-24363 affects TP-Link TL-WA855RE V5 devices running firmware 20200415-rel37464. The vulnerability is in the device's TDDP_RESET functionality, which accepts a POST request that can be invoked without authentication by an attacker on the same adjacent network. By sending this request, the attacker can force the device to perform a factory reset and reboot. After the reset, the attacker can set a new administrative password, resulting in improper access control and takeover of the device's administrative interface. The issue is consistent with missing authentication for a critical function.
