Action on a vulnerabilty found in a SMTP flow

How to configure the PA firewall to return a SMTP 541 when vulnerability is seen in a SMTP flow ? I have managed to do it with the AV protection but not with the vulnerability protection.




That's exactly my problem with PAN-OS 6.1. I was hoping 7.1 solved that issue but it looks like it is not the case ?

Hi @aroos_dts , @Cedricd,


I might have mixed up virus/vulnerability in my previous comment 😕


It actually depends if the email is identified as virus or as vulnerability.

Note that in Antivirus profile you have an SMTP decoder (you don't have this decoder in Vulnerability profiles).  

The article posted earlier does mention that it only applies to the SMTP decoder.


With the correct action of "reset-both" in the SMTP decoder you will get the 541 response.

However, in the vulnerability profile, there is no such thing as an SMTP decoder so you will get a TCP reset.


The good news is that there is already a feature request to add this functionality to Vulnerability profiles (FR #6548).   You can reach out to your local SE and ask him to add your vote to this feature.


Kind regards,

I've just come across this very issue.  Kind of a pain.  Any update on the feature request?
