OWASP_Managed Issues

Good morning,

 

We recently had issues with F5-OWASP_Managed which blocked requests that were previously allowed.

Blocking Rule : F5-OWASP_Managed 
Action : BLOCK
Rule Group ID= F5#OWASP_Managed
Terminating Rule =General_Protection_AllQueryArguments_Body

We haven't made any changes from our end. Are there any changes from F5? IF it possible, please provide solution to fix this issue.

 

Thanks,

    Hi Paul,

     

    You would need to provide more details to try and determine what happened.  Have you opened a case with support?  What is your attack signature staging posture?  Were any recent signatures now in enforcement?
