Atomicorp.com WAF Rules - Virtual Patch: PHP Easter Egg Access
This rule detects attempts to determine the version of PHP a system is using. PHP contains several "easter eggs" that can be sent to any PHP application to determine what version of PHP a system is using, even if PHP is configured to not reveal its version or other information.
This rules works by detecting the use of these easter eggs, which are PHP session IDs reserved as easter eggs. The easter eggs are referenced in the section "Outside References" at the end of this article.
There are no known false positives for this condition. If you believe your version of PHP is not vulnerable to this probe, then disable this rule. We do not recommend you do this without first testing your PHP implementation against the known probe easter eggs.
Please see the Tuning the Atomicorp WAF Rules page for basic information.
