For more information, see: http://www.webmin.com/updates.html http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0101 SGI has investigated the issue and recommends the following steps for neutralizing the exposure. It is HIGHLY RECOMMENDED that these measures be implemented on ALL vulnerable SGI systems. These issues have been corrected with the 6.5.20 webmin 1.070 package and in future releases of IRIX. - -------------- - --- Impact --- - -------------- The websetup package is installed by default on IRIX 6.5 systems as "websetup.sw.eoe". To determine the version of IRIX you are running, execute the following command: # /bin/uname -R That will return a result similar to the following: # 6.5 6.5.19f The first number ("6.5") is the release name, the second ("6.5.16f" in this case) is the extended release name. The extended release name is the "version" we refer to throughout this document. To see if websetup is installed, execute the following command: $ versions -b websetup I = Installed, R = Removed Name Date Description I websetup 11/19/2002 Web Setup and Administration, 3.4 If the result is similar to the above, then websetup is installed and the system may be vulnerable. - ---------------------------- - --- Temporary Workaround --- - ---------------------------- There is no effective workaround available for these problems if you want to use the websetup package. If you don't need it, then you can remove the package with "versions remove websetup". SGI recommends either upgrading to IRIX 6.5.20, or installing the websetup v 3.5 package from the listing below. - ---------------- - --- Solution --- - ---------------- SGI has provided the websetup v3.5 package from IRIX 6.5.20 Apps CD for these vulnerabilities. Our recommendation is to upgrade to IRIX 6.5.20 when available, or install the upgraded websetup package. OS Version Vulnerable?
