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.
A vulnerability exists in the firmware for the Xerox 4595 Copier/Printer. If exploited, this vulnerability could cause a denial of service condition that causes the device to restart. Customer and user passwords are not exposed. This firmware release can only be installed by a Xerox Customer Support Engineer; please contact the Xerox Support Center to schedule the installation.
A persistent cross site scripting vulnerability exists in the web server of the Xerox 4110 Copier/Printer, the Xerox 4590 Copier/Printer, and the Xerox 4595 Copier/Printer. If exploited, this vulnerability could allow code injection by malicious web users into the web pages viewed by other users.
