Brief camera hang via invalid URL parameter
Published Jun 9, 2021 · Updated Sep 16, 2024
Denial of service in Bosch CPP Firmware on IP cameras allows remote authenticated users with administrator rights to briefly hang a camera. An affected web endpoint handles an invalid URL parameter by driving uncontrolled resource consumption, leaving the device unresponsive for several seconds; Bosch has not disclosed the endpoint or lower-level operation. Exploitation requires network access and an administrator-authenticated camera session, and the reported consequence is a temporary service interruption.
