Sid:
661

--
Summary:
This event is generated when an attempt is made to exploit a problem with Majordomo software that allows arbitrary commands to be executed on the server.

--
Impact:
Attempted administrator access.  This is an attempt to execute a command on a server where Majordomo is installed. 

--
Detailed Information:
Majordomo is an application that automates mailing list management.  An input validation error allows attackers to use a malformed email header as a command that will be executed on the host.  To be vulnerable, the server must use a list or a hidden list and the configuration file must specify an advertise or noadvertise option.  This has been documented as either a local or remote attack on the host. 

--
Affected Systems:
Majordomo versions up to and including 1.94.4.

--
Attack Scenarios:
An attacker can send a malformed e-mail header to the Majordomo host.  The host executes a command that facilitates access to the host.


--
Ease of Attack:
Simple. Use an appropriate malformed header and supply a command that enables access to the host. 

--
False Positives:
None Known.

--
False Negatives:
None Known.

--
Corrective Action:
Upgrade to Majordomo version 1.94.5 or higher.
