That is the most horrible web-app I've seen in a long, long time.

I wonder how susceptible it is to cross-site scripting... :)

Looks like the function() { is what is triggering the rule.



Current rule



alert tcp $EXTERNAL_NET any -> $HOME_NET $HTTP_PORTS (msg:"OS-OTHER Bash
CGI environment variable injection attempt"; flow:to_server,established;
content:"() {"; fast_pattern:only; http_uri; metadata:policy balanced-ips

reference:cve,2014-7169; classtype:attempted-admin; sid:31977; rev:4;)



Will adding content:!” function() “ break things?
