Local LiveUpdate server username / password information revealed by client

Discovery Date:
August 31, 2005 - Bugtraq posting (Vulnerability in Symantec Anti Virus Corporate Edition v9.x)

Revision History

Risk Impact

Remote AccessYes
Local AccessYes
Authentication RequiredYes
Exploit publicly availableNo

LiveUpdate server login name and password are written to a local log file in clear text. This happens when the LiveUpdate client checks for updates from the server. This is only an issue when a local LiveUpdate server is used with a login name and password.

The login name and password belong to the account configured by the LiveUpdate server administrator for accessing LiveUpdate packages. Symantec strongly recommends that this user account be unique for accessing LiveUpdate packages only, and have no other system access. The system administrator account should never be used for this purpose.

Note: As stated in the LiveUpdate download readme file: LiveUpdate version 2.7.x does not support the LiveUpdate Administration Utility, Version 1.5.x. If you are running a system as a Central LiveUpdate server please go to http://www.symantec.com/techsupp/files/lu/lu.html and download Version update for the LiveUpdate Administration Utility.
