Vulnerability in TP-Link Tapo C500 (CVE-2026-104945)
Summary
Vulnerability in TP-Link Tapo C500 (CVE-2026-104945). Risk of unauthorized operations or information disclosure.
Original description
The description as published by the source.
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.
