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.
