TP-Link Tapo C500 v2.0 contains an out-of-bounds stack write vulnerability in its ONVIF PTZ SOAP handlers. An authenticated ONVIF client can submit an excessive number of preset-related elements, causing writes beyond the bounds of fixed-size stack arrays and resulting in a crash of the affected service. Successful exploitation may allow an authenticated attacker to cause the affected service to crash, resulting in a denial-of-service condition. Repeated exploitation may repeatedly disrupt camera management and PTZ-related functionality until the service recovers or restarts.
