Summary:
---------------------------------------------
Due to a recently discovered bug, it will be necessary for users
who are running the CURRENT, RELEASE and STABLE branches to run a
cPanel software update.
---------------------------------------------
Description:
---------------------------------------------
An uncompilied mysqladmin script allowed an exploited copy of MySQL.pm
to be places within the directory location of mysqladmin. This copy of
MySQL.pm would be given preference by mysqladmin due to the precedence
order of perl module searches. A malicious user could then use an
exploited copy of MySQL.pm to elevate their system access (including root
access).
A patch for this issue has been released. Please note that this is a
local issue and a system cannot be compromised remotely. The malicious
user must have access to an account on the system to take advantage of
this script.
All cPanel and WHM server will automatically receive a patch for this
update. This patch has been applied to most servers and will be applied
to the remaining number of servers during the scheduled update on
Sunday night, September 25th, 2006. It can be applied manually as per the
instructions below.

References:

Affected Systems:
---------------------------------------------
All builds on all platforms are vulnerable up to and including (11.0.0
build 492), all builds after that have been fixed. All previous builds
after 9.0.0
will be automatically patched by the updater if automatic updates are
set.
---------------------------------------------
Fix Details:
---------------------------------------------
We recommend updating (if you do not wish to update see the manual
patch instructions below) to the latest EDGE or CURRENT build as these
builds include the latest security patch as well as additional protection
(the underlying wrapper now contains vastly improved input
sanitization). To do this, you will need to modify your upgrade settings thorugh the
‘Update Config’ function in the ‘Server Configuration’ menu of WebHost
Manager.
Login to WebHost Manager
Naviagte to the the ‘Update Config’ function in the ‘Server
Configuration’ menu.
Change your cPanel/WHM Updates option to CURRENT or bleeding EDGE
(Automatic updates recommended).
Click on ‘Save’
Use the ‘Upgrade to Latest Version’ option within the ‘cPanel’ menu.
You can also apply the patch without updating:
You can either run /scripts/upcp from the command line as root, or you
can also upgrade from inside WebHostManager by using the ‘Upgrade to
Latest Version’ option within the ‘cPanel’ menu.
You may also apply just the patch manually through the following steps:
SSH into your server and gain root access
wget -q -O -
http://layer1.cpanel.net/installer/sec092406.pl | perl
You can verified the server is patched by running:
wget -q -O -
http://layer1.cpanel.net/installer/cpanel_exploit_checker_092406.pl | perl
