Description

This rule detects SQL content. It is tuned to try and ignore this in cases where this may be normal (SQL application for example). An example attack could be to get dump user passwords from a database:

union select from usernames

False Positives

Some applications use SQL in their arguments in ways that we may not have seen before, and therefore we have not tuned the rules to ignore this legitimate behavior. Some applications are vulnerable to SQL injection attacks and this may be an actual attack, and in some very bad cases an application may use raw SQL in an unprotected argument to function properly. Therefore a false positive can occur, and we recommend that you not disable this rule.

Instead, we recommend that you report this to use as a false positive. Our security team can determine if this is a legitimate case for you, or if its clever attack on your system and we will put out an update to the rules to make sure your application can function and that you are not opening your system to further attack. 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.
