Xerox Security Bulletin XRX14-008
Bash Shellshock Command Line Interpreter Vulnerability
A vulnerability has been discovered in the Bash command shell that can allow attackers to remotely execute commands on a target system. Even systems that donâ€™t allow remote command shell connections may still use Bash to execute commands in the Apache web server and other network-facing applications. Unix and Unix-derived systems like Linux and Mac OS X are vulnerable to these attacks since they use Bash as the default command shell.
A Bash Shellshock document addressing this vulnerability has been posted to the Xerox Security Site.
NOTE: Review the bulletin for a more complete list of devices.
The Xerox devices ColorQubeÂ® 9201/9202/9203, ColorQubeÂ® 9301/9302/9303, WorkCentreÂ® 232/238/245/255/265/275, WorkCentreÂ® 5030/5050, WorkCentreÂ® 5135/5150, WorkCentreÂ® 5632/5638/5645/5655/5665/5675/5687, WorkCentreÂ® 5735/5740/5745/5755/5765/5775/5790, WorkCentreÂ® 6400, WorkCentreÂ® 7525/7530/7535/7545/7556, WorkCentreÂ® 7655/7665/7675, WorkCentreÂ® 7755/7765/7775, WorkCentreÂ® Bookmark 40/55, WorkCentre ProÂ® 232/238/245/255/265/275 were shipped with certain protocols enabled that, if properly exploited, could be used to gain
unauthorized access to the system. These particular protocols should not have been present in the production configuration and need to be removed from that configuration to minimize the possibility of unauthorized system access.
A software solution (patch P49) is provided for the products listed. This solution will remove from the production configuration the unwanted protocols in question so they canâ€™t be exploited to gain unauthorized access to the system.
This solution is designed to be installed by the customer. The software solution is compressed into a 3 KB zip file and can be accessed via the link below or via the link following this bulletin announcement on the Xerox Security Site.

NOTE: We are re-issuing this bulletin due to a spelling error of the name of one of the researchers. No technical content in the bulletin has changed.
Vulnerabilities exist that, if exploited, could allow remote attackers to insert arbitrary code into the device. This could occur with a specifically crafted Postscript or firmware job submitted to the device. If successful, an attacker could make unauthorized changes to the system configuration; however, customer and user passwords are not exposed.
As part of Xeroxâ€™s on-going efforts to protect customers, the ability to accept these specially crafted jobs can be disabled for the affected products listed in the bulletin. Links for the software needed are contained inside the bulletin.
Original Release January 22, 2010
Vulnerabilities exist in the Network Controller and Web Server of the WorkCentre 5632/5638/5645/5655/5665/5675/5687, WorkCentre 5030/5050, WorkCentre 5135/5150, WorkCentre 6400, WorkCentre 7655/7665/7675, WorkCentre 7755/7765/7775, WorkCentre/WorkCentre Pro 232/238/245/255/265/275 and ColorQube 9201/9202/9203 products. If exploited these vulnerabilities could permit an attacker to either bypass Scan to Mailbox authorization to access mailboxes stored on the device or bypass web server authorization to view device configuration settings. Customer and user passwords are not exposed.
Second Release September 29, 2009
Original Release August 28, 2009
A vulnerability exists in the web servers of the WorkCentre 5030/5050, the WorkCentre 5135/5150, the WorkCentre 5632/5638/5645/5655/5665/5675/5687, the WorkCentre 7655/7665/7675, the WorkCentre 6400, and the ColorQube 9201/9202/9203. If exploited when SSL is not enabled on the device, the vulnerability could allow remote attackers to obtain unauthorized access to device configuration settings, possibly exposing customer passwords
NOTE: The original version of the P39 patch required a manual reboot after installation. This version of the patch automatically performs a re-boot upon installation.
