The Xerox devices ColorQube® 9201/9202/9203, ColorQube® 9301/9302/9303, WorkCentre® 232/238/245/255/265/275, WorkCentre® 5030/5050, WorkCentre® 5135/5150, WorkCentre® 5632/5638/5645/5655/5665/5675/5687, WorkCentre® 5735/5740/5745/5755/5765/5775/5790, WorkCentre® 6400, WorkCentre® 7525/7530/7535/7545/7556, WorkCentre® 7655/7665/7675, WorkCentre® 7755/7765/7775, WorkCentre® Bookmark 40/55, WorkCentre Pro® 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 can’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.

The vulnerability documented in CVE-2011-3192 exists in the Web Server of the WorkCentre 5135/5150, and the WorkCentre 5632/5638/5645/5655/5665/5675/5687 models. If exploited the vulnerability could allow remote attackers to create a Denial of Service on the device.
A software solution (patch P50) is provided below. This solution is designed to be installed by the customer. Please follow the procedures in the bulletin to install the solution to protect your product from possible attack through the network.
The software solution is compressed into an 5.2 MB 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 Xerox’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 June 18, 2010 System Software Version 021.120.060.00015 for the WorkCentre 5632-5687 Multi-Board controller and WorkCentre 5135/5150 models and System Software Version 025.054.060.00015 for the 5632-5655 Single Board controller models is a cumulative update that incorporates several security vulnerability fixes as well as other non-security related defect fixes. Both devices have been recertified to Common Criteria EAL Level 3. Both releases have been submitted for Common Criteria certification, which is expected to be completed by September 2010.
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.
A command injection vulnerability exists in the web server of the WorkCentre/WorkCentrePro 232/238/245/255/265/275, the WorkCentre 7655/7665/7675, and the WorkCentre 5632/5638/5645/5655/5675/5687. if exploited, the vulnerability could allow remote attackers to execute arbitrary code via carefully crafted inputs on the affected web page. 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.
A vulnerability exists in the WorkCentre Pro 232/238/245/255/265/275, WorkCentre 232/238/245/255/265/275, WorkCentre 7655/7665/7675, and WorkCentre 5632/5638/5645/5655/5665/5675/5687 ESS/Network Controller that, if exploited, could allow remote attackers to execute arbitrary code via specially crafted Remove Service Message Block (SMB) responses. This could occur with buffer overflows and un-validated user input in the Samba third-party code that handles file and printer sharing services for SMB clients (including Xerox MFD devices).
If successful, an attacker could make unauthorized changes to the system configuration; however, customer and user passwords are not exposed. This vulnerability affects only the printer sharing services.
As part of Xerox’s on-going efforts to protect customers, a patch is being provided for customers interested in the Common Criteria Certified version, 21.113.02.000, for the WorkCentre 56xx products that adds improved audit logging to meet the requirements of NIAP Policy #15.
