This protocol anomaly triggers when it detects an HTTP directory traversal attempt, i.e. /../ or /./. This can indicate an attempt to evade an IDS (IDP is not vulnerable). Note that some Web sites refer to directories in a way that looks like a traversal.
An HTTP request that contains a parent directory string could indicate an attempt to perform an unauthorized directory traversal is underway.
