Title: Microsoft Windows 2000 Default 40-bit Encrypted Protected Store Vulnerability
Severity: MODERATE
Description:
Windows 2000 Protected Store uses a default 40-bit encryption instead of utilizing the stronger 56-bit DES encryption that it is shipped with, or 168-bit Triple DES (if Windows 2000 has been upgraded using the High Encryption Pack). A remote or local user who posesses full administrative rights can use decryption utilities against the weakly encrypted Protected Store in order to obtain user private keys.
