Authenticated Format String Injection on TP-Link Tapo C110_CVE-2026-6250

7 / 10

HIGH

CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N

Description

An
authenticated format string vulnerability exists in the ONVIF service of Tapo
C110 v2 due to improper handling of user-controlled input. Externally controlled data is interpreted as
a format string, which can be used to manipulate stack memory, including
control flow data such as return addresses.

A remote
authenticated attacker may redirect execution flow to existing internal
functions, triggering an unauthorized factory reset, leading to loss of
configuration, deletion of stored credentials and service disruption.
