Cobalt Networks -- Security Advisory -- 5.25.2000
Problem: With the current installation of Frontpage on RaQ2 and RaQ3, the ability to write data to other websites hosted on the same RaQ. This is due to a permissioning issue with the 'httpd' user.

When a site is uploaded with FP to a RaQ2/3, all of the files are owned by user "httpd" instead of a site-specific user. The Apache web server is also running as user "httpd". Cobalt uses cgiwrap to have CGIs run as the user that owns the CGI instead of "httpd", but it is trivial to bypass cgiwrap and run scripts as user "httpd".
Cobalt Networks is dedicated to providing secure platforms. Accordingly, we have just completed a fix for this bug that is available in tar.gz format, which can be found at the following locations:
RaQ 3i (x86) tar.gz: ftp://ftp.cobaltnet.com/pub/experimental/secuirty/frontpage/fpx_patch1.tar.gz
RaQ 2 (MIPS) tar.gz: ftp://ftp.cobaltnet.com/pub/experimental/secuirty/frontpage/fpx_patch1.tar.gz
You can verify each rpm using the following command: md5sum fpx_patch1.tar.gz
The details on installing this package are located at: ftp://ftp.cobaltnet.com/pub/experimental/secuirty/frontpage/README
The package file format (pkg) for this fix is currently in testing, and will be available in the very near future.
