Multiple buffer overflows in FTP Print Server 2.4 and 2.4.5 in HP LaserJet 5000 Series printers with firmware R.25.15 or R.25.47, and HP LaserJet 5100 Series printers with firmware V.29.12, allow remote attackers to cause a denial of service (device crash) via a long string in the (1) LIST or (2) NLST command.

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.

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.
