CirrostratusCVE-2018-9126 - DotNetNuke DNNarticle Directory Traversal
Is there any signature for CVE-2018-9126 provided by F5 ?
if yes , then what is the name of signature so that we can enforce it in ASM ?

in lieu of a signature, this should be an easy block by adding a disallowed parameter as such:
CP=%2fweb.config
THE_BLUEbut is this mean there is no pre-defied signature from F5 ASM ?
if i have not add this parameter as disallowed, does ASM will pass the traffic with no block ?

You can check your signatures to find out by following the guidance here: https://support.f5.com/csp/article/K45558510
if there is a signature and you’ve applied it it should block. If there is no signature you will need to add a parameter to do so.
