- 受影响的程序版本

Bardon Data Systems WinU 5.1
- Microsoft Windows 2000 Professional
- Microsoft Windows 95
- Microsoft Windows 98
- Microsoft Windows NT 4.0

- 漏洞讨论

Bardon Data Systems WinU is a full Windows 95/98/NT user interface replacement with added security features.

Versions of WinU prior to 5.2 utilizes a weak encryption scheme to encode its administrative password. The password is stored under HKEY_CLASSES_ROOT\WinU4\Config or HKEY_CLASSES_ROOT\WinU5\Config (depending on the version).

For versions 4.x - 5.0 of WinU, the encryption formula is as follows:

154 - ascii code value = encrypted value

Therefore, the letter "A" whose ascii code value is 65 would appear as 89 in encrypted form. The password is then reversed to further obfuscate the original value.

For version 5.1 of WinU, the encryption formula is as follows:

ascii code value + 101 = encrypted value

Deciphering the administrative password would yield full control over the WinU interface.
