Unauthenticated Wi-Fi credential disclosure via getSysStatusCfg
Published Apr 8, 2024 · Updated Aug 2, 2024
Information disclosure in TOTOLINK EX200 4.0.3c.7646_B20201211 allows remote attackers to read Wi-Fi credentials without authentication. The getSysStatusCfg function returns the configured Wi-Fi SSID and password even when the requester has not logged in through /login.asp. Network access to the extender web interface is sufficient, and the documented impact is limited to disclosure of the wireless network name and password.
