Alert Message
Atomicorp.com WAF Rules: Too many arguments in request (max set to 1000, increase as necessary for your system)
Description
This rule simply detects if a single request has more that 1000 arguments. This rule is designed to help protect your system from certain Denial of Service (DOS) attacks, such as the PHP Hash DOS attack.
False Positives
This rule has no known false positives. If this rule is triggered, it means the request has more than 1000 arguments. If this is too low of a value for your application, then either disable this rule for the domain or increase the limit by following the advice in Tuning Recommendations below.
If you believe this is a true false positive, that is the request does not have 1000 arguments, please report this to our security team. Instructions to report false positives are detailed on the Reporting False Positives wiki page.
Tuning Recommendations
If you wish to tune this rule yourself, please see the Tuning the Atomicorp WAF Rules page for basic information. In the case of this rule, if you wished to increase the number of arguments do not modify the rule itself, ASL will overwrite updates to the rules if you tell it to update its rule. Instead, follow the recommendations on the Tuning the Atomicorp WAF Rules page, disable this rule globally, and create a custom version of this rule for your system.
If you do not wish to restrict the number of arguments in a request, just disable this rule.
