The IIS web server may allow remote users to read sensitive information
from .cnf files. This is not the default configuration.

Example, http://target/_vti_pvt%5csvcacl.cnf, access.cnf,
        svcacl.cnf, writeto.cnf, service.cnf, botinfs.cnf,
        bots.cnf, linkinfo.cnf and services.cnf

Solution: If you do not need .cnf files, then delete them, otherwise use
suitable access control lists to ensure that the .cnf files are not
world-readable by Anonymous users.

Risk factor : Medium";
