TITLE

FXPS In the print engine FTP Vulnerability using print interface as proxy

DESCRIPTION

Fuji Xerox Printing Systems (FXPS) print engine, as used in products including (1) Dell 3000cn through 5110cn and (2) Fuji Xerox DocuPrint firmware before 20060628 and Network Option Card firmware before 5.13, allows remote attackers to use the FTP printing interface as a proxy ("FTP bounce") by using arbitrary PORT arguments to connect to systems for which access would be otherwise restricted. This could result in the proxying of arbitrary requests by a user through the system using the vulnerable FTP print server. Successful exploits may allow an attacker to make connections to arbitrary hosts and generate traffic with the identity of the vulnerable FTP print server. As a result, this may allow the attacker to bypass access controls and security restrictions by masking the original source of the attacker's traffic. ---------------------------------------------------------------------- Want to work within IT-Security?

This can be exploited to make unauthorized changes to the system configuration or to cause a DoS. The vulnerability has been reported in Dell 5110cn, Dell 3110cn, and Dell 3010cn with firmware versions prior to A01 and in Dell 5100cn, Dell 3100cn, and Dell 3000cn with firmware versions prior to A05. NOTE: Other products using the Fuji Xerox Printing Engine may also be affected. SOLUTION: Apply patches.

A successful attacker would be able to reset the administrator password but would not be capable of exposing the current password. Mitigation/workarounds: Disabling FTP printing prevents the FTP bounce attack. Disabling the embedded web server prevents the DoS/unauthorized configuration change attack. Best practice suggests that access controls and network firewall policies be put into place to only allow connections from trusted machines and networks. Criticality: These vulnerabilities have a combined risk of moderately critical.
