Solution for Security of a Server


I have a real problem with invasion and installing of bots for phishing on one of my servers. Due to this, it is listed in

several blacklists. Some details:

1) It is a Linux Centos Server, running Apache (version [url removed, login to view]), Sendmail (version 8.13.1), PHP4. It is something

old, and probably on next month we will be moving to a new one, with Postfix, PHP5, etc. But I have serious

problems to solve right now and can't wait.

2) It is basically a Domains Server, but it still has some mailboxes, which I am moving, on this next weekend, to

another Server, securer and running Postfix. So on next Monday it will have just Domains, no mailboxes.

3) Its Domains (hundreds) all have forms. These thousands of forms use an old Perl CGI Script (see attached files)

which has been modified along the time to add some security, but I think this has not been enough. This Script

resides at system cgi-bin directory or at some of the Domains' cgi-local directories.

4) My /var/log/maillog file is very strange, see a portion of it also in attachment. It covers today, Apr 7, just from 7am to 9am, that is, 2 early hours in the morning, a period when this Server normally never shows heavy activity.

5) At any time of the day or the night, this maillog file shows a very strong sendmail activity, as if this Server had

hundreds and hundreds of mailboxes. I assure: this Server's existing mailboxes are not enough to generate a so

intensive activity. This must be someone else using the Server for spamming, and I need to stop them.

What I need with this Bid request is in the doc attached.
