HP » Color Laserjet 9500 Mfp : Security Vulnerabilities, CVEs,

Directory traversal vulnerability in the PostScript Interpreter, as used on the HP LaserJet 4xxx, 5200, 90xx, M30xx, M4345, M50xx, M90xx, P3005, and P4xxx; LaserJet Enterprise P3015; Color LaserJet 3xxx, 47xx, 5550, 9500, CM60xx, CP35xx, CP4005, and CP6015; Color LaserJet Enterprise CP4xxx; and 9250c Digital Sender with model-dependent firmware through 52.x allows remote attackers to read arbitrary files via unknown vectors.

The HP Embedded Web Server (EWS) on HP LaserJet Printers, Edgeline Printers, and Digital Senders has no management password by default, which makes it easier for remote attackers to obtain access.

Multiple cross-site request forgery (CSRF) vulnerabilities in the HP Embedded Web Server (EWS) on HP LaserJet Printers, Edgeline Printers, and Digital Senders allow remote attackers to hijack the intranet connectivity of arbitrary users for requests that (1) print documents via unknown vectors, (2) modify the network configuration via a NetIPChange request to hp/device/config_result_YesNo.html/config, or (3) change the password via the Password and ConfirmPassword parameters to hp/device/set_config_password.html/config.
