Symantec's AntiVirus Corporate Edition 9.0 saves usernames and passwords in plain text in a log file when connecting to an internal LiveUpdate server for updates, according to a post on the Bugtraq mailing list. The credentials are stored in a fixed location on the computer that's accessible by any user, according to the bug report.
Symantec's Incident Response team has been notified of the suspected issue, a Symantec representative said on Thursday. "Symantec's product teams are evaluating the issue now and, if necessary, will provide a prompt response and solution," the representative said.
One scenario in which the user credentials could be abused is by a local attacker to gain higher privileges, according to the bug report.
As a workaround, users of AntiVirus Corporate Edition could set their systems to allow anonymous, read-only access to the LiveUpdate server, one Bugtraq reader advises. "The downside is that anyone can take a look at the state of your LiveUpdate files and might use version or product information against you in some way," the reader writes.
