Perl.Lexac is a worm that spreads to Web servers running php scripts that are vulnerable to a "File Inclusion Flaw", which results from programming errors. The worm uses the Google and Yahoo search engines to obtain a list of vulnerable computers.
Note: The File Inclusion Flaw is independent from the PHP version of the server, and results from common coding mistakes.
