How to Update
No action is required of customers that run version 7.0 of Trustwave Web Application Firewall and subscribe to the online update feature. Their deployments will receive the update automatically.
Note that even if blocking actions are defined for a protected site, simulation mode for these rules is ON by default so that site managers can inspect the impact of new rules before actually blocking relevant traffic. If you would like to activate blocking actions for this rule, you need to update the Actions for this signature in the Policy Manager.
