List of useful CXS regs commands, use it at your own risk.

If you see one that doesn't fit in your box, feel free to delete it before installing them in your CXS.XTRA file.

IMPORTANT:
Every time you include a new rule in your cxs.xtra file, run a scan on one (not all) account, so you can check if the rules are working.

Do you have a RegEX that you want to share?
Open a new post and set the subject "NEW RegEX rule" and fill the post with your RegEX, if you have more than one, write all of them in your post.

Enjoy.

regall:header\("Location: http

this shouldn't be blocked.

Nor should things like this:

Code: Select all

regall:aol.com:205.188.109.56

...unless you have a very specific and particular reason for doing so. AOL uses dynamic IPs so if an AOL user is connecting via one IP, their IP will be different the next time they connect to the internet.

Well, all this definitions are to check a file that contains that characters in it, not to block any AOL IP.

There is an exploit that sends spam, the name of the file is DA.CGI, this script calls a lot of other files and inside this files you find this AOL Address. So, if you have in your server a file that contains this expresion, it has to be investigated, then you decide to delete or not.

If you have scripts to send emails that uses an URL on the header it has to be investigated, as it could send an URL that is not in your server.

Remember that CSX is to help you to check what is being uploaded in your server, if one of your customers upload a file with this regex on it, CSX will tell you what is the code that your customer is uploading.

Sergio, you have to escape your regex's correctly otherwise you will get a lot of false-positives, or they won't work. In particular you need to escape dots and brackets, e.g.:

regall:\.ru\:8080
regall:MAILBASE=\./upload/m\.txt

Thanks Chirpy, I will do that.

Thanks Sergio i will try it

that could be used in the CSF.XTRA file

you mean cxs.xtra

Posted: **31 Jan 2010, 16:44**

What would be the bestway to add this to the extras file

we need to have the following scanned for

$mrd = trim(file_get_contents("m"));

regphp:\$mrd = trim$file_get_contents\(\"m\"$\)\;
