Summary:
This event is generated when an attempt is made to access mailfile.cgi on an internal web server. This may indicate an attempt to exploit a file disclosure vulnerability in Oatmeal Studios Mail File 1.10.

--
Impact:
Information disclosure.

--
Detailed Information:
Mail File 1.10 is a Perl script that allows web site visitors to email files to any user using an online form. It contains a vulnerability where an attacker can craft a URL with an arbitrary file name in the "filename" argument. If the file exists on the server, it is emailed to the address that the attacker specifies in the URL. 

--
Affected Systems:
Systems running Oatmeal Studios Mail File 1.10.

--
Attack Scenarios:
An attacker sends a specially crafted HTTP request to a vulnerable web server with /../../../etc/passwd as the filename argument. If the web server's password file exists at that location, it is sent to the email address specified in the URL.

--
Ease of Attack:
Simple. Exploits exist.

--
False Positives:
If a legitimate remote user accesses mailfile.cgi, this rule may generate an event.

--
False Negatives:
None known.

--
Corrective Action:
Disable mailfile.cgi.
