Title: Netwin NWAuth Weak Password Encryption Vulnerability

Severity: MODERATE

Description:

The Netwin Authentication module, or NWAuth, is an external authentication module used by several Netwin products.

A simple one-way hash function is used by NWAuth to perform password encryption operations. As a result, it is trivial for an attacker to compose a list of possible plaintext values or perform some other brute force attack against the data encrypted using the scheme.

  • NetWin DMail 2.7.0
