HP laserjet 9050 any version

The default configuration of the HP CM8060 Color MFP with Edgeline; Color LaserJet 3xxx, 4xxx, 5550, 9500, CMxxxx, CPxxxx, and Enterprise CPxxxx; Digital Sender 9200c and 9250c; LaserJet 4xxx, 5200, 90xx, Mxxxx, and Pxxxx; and LaserJet Enterprise 500 color M551, 600, M4555 MFP, and P3015 enables the Remote Firmware Update (RFU) setting, which allows remote attackers to execute arbitrary code by using a session on TCP port 9100 to upload a crafted firmware update.

Directory traversal vulnerability in the HP JetDirect web administration interface in the HP-ChaiSOE 1.0 embedded web server on the LaserJet 9040mfp, LaserJet 9050mfp, and Color LaserJet 9500mfp before firmware 08.110.9; LaserJet 4345mfp and 9200C Digital Sender before firmware 09.120.9; Color LaserJet 4730mfp before firmware 46.200.9; LaserJet 2410, LaserJet 2420, and LaserJet 2430 before firmware 20080819 SPCL112A; LaserJet 4250 and LaserJet 4350 before firmware 20080819 SPCL015A; and LaserJet 9040 and LaserJet 9050 before firmware 20080819 SPCL110A allows remote attackers to read arbitrary files via directory traversal sequences in the URI.

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.

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