This signature detects attempts to exploit a known cross-site scripting vulnerability against PHP. It is due to insufficient validation of user-supplied input. Attackers can steal cookie-based authentication credentials and launch other attacks.
It is reported that it is possible to bypass PHPs strip_tags() function. It is reported that under certain circumstances, PHPs strip_tags() function will improperly leave malformed tags in place. This vulnerability may mean that previously presumed-safe web applications could contain multiple cross-site scripting and HTML injection vulnerabilities when viewed by Microsoft Internet Explorer or Apple Safari web browsers. It is reported that 'magic_quotes_gpc' must be off for PHP to be vulnerable to this issue.
