Details
When an authenticated password change request takes place, this vulnerability could allow the attacker to intercept the message that includes the legitimate, new password hash and replace it with an illegitimate hash. The user would no longer be able to authenticate to the controller (Micro800: All versions, MicroLogix 1400: Version 21 and later) causing a denial-of-service condition
