In the past week, I have received a plethera of alerts with this High Level title. After blacklisting the host IP it is back with a different one. I am starting to get concerned because the first IP address that was blacklisted was a hacker.
Can someone tell me if this is a false positive or not?
That signatures fires on a match of an attempt to call the awstats.pl cgi script with a parameter of configdir and a parameter value containing a ";" or "|". It seems pretty unlikely to be a false positive in the sense that it is probably not legitimate traffic. It isn't necessarily a hacker targeting your systems...it may just be a worm or script that scans the Internets looking for vulnerable systems.
