1. Topic:
cachemgr.cgi, the manager interface to Squid, is installed by default in /home/httpd/cgi-bin. If a web server (such as apache) is running, this can allow remote users to sent connect() requests from the local machine to arbitrary hosts and ports.

2. Bug IDs fixed:

3. Relevant releases/architectures:
Red Hat Linux 6.0, all architectures

4. Obsoleted by:
None

5. Conflicts with:

6. RPMs required:

Intel:

7. Problem description:
A remote user could enter a hostname/IP address and port number, and the cachemgr CGI would attempt to connect to that host and port, printing the error if it fails.

8. Solution:
For each RPM for your particular architecture, run:

rpm -Uvh filename

where filename is the name of the RPM.

Alternatively, you can simply disable the cachemgr.cgi, by editing your http daemons access control files or deleting/moving the cachemgr.cgi binary.

After installing the rpm, please restart squid by typing:

/etc/rc.d/init.d/squid restart

9. Verification:
