TP-Link Tapo\nC500 v2.0 contains an out-of-bounds stack write vulnerability in its ONVIF PTZ\nSOAP handlers. An authenticated ONVIF client can submit an excessive number of\npreset-related elements, causing writes beyond the bounds of fixed-size stack\narrays and resulting in a crash of the affected service.
\n\n
Successful\nexploitation may allow an authenticated attacker to cause the affected service\nto crash, resulting in a denial-of-service condition. Repeated exploitation may\nrepeatedly disrupt camera management and PTZ-related functionality until the\nservice recovers or restarts.
