The embedded HTTP server in 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, does not properly perform authentication for HTTP requests, which allows remote attackers to modify system configuration via crafted requests, including changing the administrator password or causing a denial of service to the print server.
CWE-287 - Improper Authentication
Improper (or broken) authentication attacks are widespread, and have accounted for many of the worst data breaches in recent years. Improper authentication attacks are a class of vulnerabilities where an attacker impersonates a legitimate user by exploiting weaknesses in either session management or credential management to gain access to the user’s account. This can result in disclosure of sensitive information, and can lead to system compromise, theft, identity theft, and fraud.
