create new vuln profile (that does not have this in exception),ĥ. make an exception in all existing vuln profiles for this signature (you don't want it catching everything and anything before you test it!),Ĥ. simple vulnerability signature catching onto fixed string, something like "subject",ģ. custom but simple application for pop3, as explained, just defining tcp/110,Ģ. I really don't have any pop3 service running or configurable to test this with, but there MUST be some string in email header that you can grab for this? (I still am not sure if my proposal works as I can't test it)ġ.
You can use regex together with that anchor, but you must have a 7-byte anchor. For what it's worth, I think your signature is mostly valid but it has some extra spaces and it also should probably escape brackets, I am not completely sure what are you trying to match, do you need brackets or not? Anyways, that is regex-wise for PAN-OS you are failing to meet another requirement: Problem you are seeing is that for any custom signature, you have to have at least 7 bytes of fixed string that must be fixed so no regex can be used WITHIN those 7 characters / bytes.
