Executive Summary

This vulnerability exists in Foscam Video Management System version 1.1.6.6 and is a buffer overflow issue in the UID field.

Local attackers can exploit this by supplying an excessively long string—specifically, a 5000-character buffer—into the UID parameter during device addition.

When the Login Check function processes this input, it triggers an application crash due to the buffer overflow.

Impact Analysis

The primary impact of this vulnerability is that local attackers can cause the Foscam Video Management System application to crash.

This denial of service (DoS) condition can disrupt normal operation of the video management system, potentially affecting surveillance and monitoring capabilities.

However, the vulnerability does not impact confidentiality or integrity, as it does not allow data disclosure or modification.
