Horde arbitrary file inclusion vulnerability
March 7th, 2008
An arbitrary file inclusion vulnerability has been discovered in the Horde webmail application. This security vulnerability affects Horde v3.1.6 and earlier. In addition, the cPanel engineers believe that this security threat affects Horde Groupware v1.0.4 and earlier as well (cPanel does not use Horde Groupware at this time).
cPanel customers should update their cPanel/WHM servers immediately to prevent any chances of server compromise. The patch will be available in builds 11.18.2 and greater (or 11.19.2 and greater for EDGE systems). The updated builds will be available immediately to all fast update servers.
To check which version of cPanel/WHM you currently have on your server, log into your WHM and look in the top right corner, or run the following command from the command line as root:
/usr/local/cpanel/cpanel -V
HowTo Update your cPanel/WHM
Login to WHM >> and find 'Upgrade to Latest Version' in the left pane/frame; or by executing the following from the command line as root:
/scripts/upcp --force
We suggest that all use of Horde v3.1.6 and earlier be stopped (on cPanel and non-cPanel systems alike) until Horde updates can be applied. To disable Horde on a cPanel powered server, Login to the WHM and un-check the checkbox next to 'Server Configuration' >> 'Tweak Settings' >> 'Mail' >> 'Horde Webmail', scroll down the page and press the button "Save".

*** If you're HOSTING your server with ServerTune, we can apply these updates FREE of charge. Just submit a ticket via http://ServerTune.com/help/ ***
The Horde webmail application framework has been updated to v3.1.7 for the official fix to the previously announced arbitrary file inclusion vulnerability. cPanel has also made upgrades in cPanel's PHP application security model for Horde, PhpMyAdmin, and PhpPGAdmin. These upgrades have been made to minimize or mitigate undiscovered vulnerabilities in these third-party applications while running within a cPanel installation.
We suggest you update your cPanel powered server to either v1.18.3 or v11.19.3. If you do not wish to update the cPanel, it is strongly recommended that you keep Horde disabled until these updates have been applied.
