Description

This rule is detecting the use of path recursion in an Argument or in the URI. This rule attempts to detect encoded recursions, an example of a recursion attack may look like:

../..

An example attack could be to get to a protected file on the system. For example:

../../../../../etc/passwd

False Positives

Some applications may use recursions to get some files. Therefore a false positive can occur. It is not recommended that you disable this rule. If this is a false positive, please report this to our security team can determine if this is a legitimate case, or if its clever attack on your system. Instructions to report false positives are detailed on the Reporting False Positives wiki page.

If you wish to tune this rule yourself, please see the Tuning the Atomicorp WAF Rules page for basic information.
