Until an official fix is released, restrict network access to the WebCam Server Login interface to trusted users only and monitor for suspicious HTTP requests attempting to exploit this vulnerability. Avoid exposing the affected service directly to untrusted networks.
Description
A stack overflow vulnerability exists in the WebCam Server Login functionality of GeoVision GV-VMS V20 20.0.2. A specially crafted HTTP request can lead to an arbitrary code execution. An attacker can make an unauthenticated HTTP request to trigger this vulnerability. #### Stack-overflow via unconstrained sscanf The call to `sscanf` at [1] to split the `Buffer` variable into the `username` and `password` variables doesn't limit the size of the extracted content to match the destination buffers' sizes. In this case, if either the username or password decoded from the authorization string exceeds `40` characters (the size the stack variables `username` and `password`) then a stack overflow will occur. The data is controlled by an attacker, but sronger constraints (e.g.no null bytes) may make exploitation harder. A successful attack could lead to full code execution as SYSTEM on the machine running the service.
