Vulnerability Assessment Details
Checks whether the cachemgr.cgi is installed and accessible.
Detailed Explanation for this Vulnerability Assessment
RedHat Linux 6.0 installs by default a squid cache manager cgi script with
no restricted access permissions. This script could be used to perform a
port scan from the cgi-host machine.
If you are not using the box as a Squid www proxy/cache server then
uninstall the package by executing:
rpm -e squid
If you want to continue using the Squid proxy server software, make the
following actions to tighten security access to the manager interface:
mv /home/httpd/cgi-bin/cachemgr.cgi /home/httpd/protected-cgi-bin/
And add the following directives to /etc/httpd/conf/access.conf and
--- start access.conf segment ---
# Protected cgi-bin directory for programs that
# should not have public access
deny from all
permit from localhost
#permit from .your_domain.com
--- end access.conf segment ---
--- start srm.conf segment ---
ScriptAlias /protected-cgi-bin/ /home/httpd/protected-cgi-bin/
--- end srm.conf segment ---
