I think that this would be a valid use-case to allow gid:3 rules to be modified, consider it a feature request that we will work into the tool.

good.
Recently I noticed that snort rule 3-10481 (Squid NTLM Exploit Rule) is defined only for port 3128. But, here we have proxies running on many different ports, so I decided
to
change the rule from $external_net 3128 to $external_net
[3128,xxxx,yyyy].
However, the modifysid.conf file explicitly stated that any changes will only occur to gid:1 files and not gid:3 stubs(Since they are
inconsequential
or such stuff). I tried making an entry in modifysid.conf for said rule,
but
it didn't fire. So, I manually changed the rule line and restarted snort. Earlier the Squid NTLM exploit when fired from Metasploit on port xxxx
was
not detected. But now, since I had modified the so_rule stub to include
xxxx
in the port part, it was detected. So, my question is why doesn't pulledpork modify stubs of rules with
gid:3
(atleast parts such as home_net external_net, source,dest ports etc) when clearly such changes reflect in snort's behaviour Regards, Dheeraj -- To iterate is human.To recurse, divine!
