Symantec LiveUpdate stores proxy server passwords in plaintext in registry

Vulnerability Note VU#814187

Original Release Date: 2001-07-20 | Last Revised: 2006-05-09


A vulnerability exists in the way Symantec LiveUpdate stores proxy server passwords which could allow local users to have read access to the key.


LiveUpdate version 1.5 stores proxy server passwords in clear text in the registry, under HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\LiveUpdate\Preferences\Proxy. All users on the machine have read access to this key. The concern is that the proxy server user name and password might be the same as the user name and password for logging onto the domain.

For more information, please see the SARC Security Advisory.


This vulnerability could allow a local attacker to view the proxy server password.


Update to LiveUpdate 1.6 or later.
