TCP_CVS invalid module response

 

Code: p535

Severity: Notice

 

Description: CVS is the Concurrent Versions System, commonly used to help manage software development.

Impact: This may be an intelligence gathering activity or an attempt to view a module the user does not have access to. Should this attempt be succesful the entire CVS repository may be compromised.

Corrective: Disable the CVS daemon in the file /etc/inetd.conf. Run the CVS daemon as a user other than root that does not have a valid login to the machine. Disable anonymous cvs access to the server where appropriate. Maintain checks on the password database and the CVS repository.
