Descriptions

A vulnerability regarding authentication bypass by spoofing is found in the RTSP functionality. This allows man-in-the-middle attackers to obtain privileges without consent via unspecified vectors. The following models with Synology Camera Firmware versions before 1.0.7-0298 may be affected: BC500 and TC500.

This vulnerability allows local attackers to escalate privileges on affected installations of Synology BC500 cameras. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within the implementation of user accounts. The issue results from the lack of proper configuration for non-admin accounts. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of root.
