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.

The PML Driver HPZ12 (HPZipm12.exe) in the HP all-in-one drivers, as used by multiple HP products, uses insecure SERVICE_CHANGE_CONFIG DACL permissions, which allows local users to gain privileges and execute arbitrary programs, as demonstrated by modifying the binpath argument, a related issue to CVE-2006-0023.

Directory traversal vulnerability in the HP Color LaserJet 2500 Toolbox and Color LaserJet 4600 Toolbox on Microsoft Windows before 20060402 allows remote attackers to read arbitrary files via a .. (dot dot) in an HTTP GET request to TCP port 5225.

The remote upgrade capability in HP LaserJet 4200 and 4300 printers does not require a password, which allows remote attackers to upgrade firmware.
