 desc["english"] = "
The remote host seems to be vulnerable to a security problem in 
CGIEmail (cgicso).  The vulnerability is caused by inadequate processing 
of queries by CGIEmail's cgicso and results in a command execution 
vulnerability.

Impact:
The server can be compromised by executing commands as the web server's 
running user (usually 'nobody').

Solution:
Modify cgicso.h to contain a strict setting of your finger host.

Example:
Define the following in cgicso.h:
#define CGI_CSO_HARDCODE
#define CGI_CSO_FINGERHOST 'localhost'

Risk factor : High";
