--------------------------------------------------------------------- Red Hat, Inc. Security Advisory Synopsis: Potential misuse of squid cachemgr.cgi Advisory ID: RHSA-1999:025-01 Issue date: 1999-07-29 Updated on: Keywords: squid cachemgr.cgi connect Cross references: --------------------------------------------------------------------- 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 Red Hat Linux 5.2, all architectures 4. Obsoleted by: 5. Conflicts with: 6. RPMs required: Red Hat Linux 6.0: Intel: ftp://updates.redhat.com/6.0/i386/squid-2.2.STABLE4-5.i386.rpm Alpha: ftp://updates.redhat.com/6.0/alpha/squid-2.2.STABLE4-5.alpha.rpm Sparc: ftp://updates.redhat.com/6.0/sparc/squid-2.2.STABLE4-5.sparc.rpm Source packages: ftp://updates.redhat.com/6.0/SRPMS/squid-2.2.STABLE4-5.src.rpm Red Hat Linux 5.2: Intel: ftp://updates.redhat.com/5.2/i386/squid-2.2.STABLE4-0.5.2.i386.rpm Alpha: ftp://updates.redhat.com/5.2/alpha/squid-2.2.STABLE4-0.5.2.alpha.rpm Sparc: ftp://updates.redhat.com/5.2/sparc/squid-2.2.STABLE4-0.5.2.sparc.rpm Source packages: ftp://updates.redhat.com/5.2/SRPMS/squid-2.2.STABLE4-0.5.2.src.rpm 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. 9.
