A remote attacker can bypass the System Manager Mode on the Canon LBP6030w web interface without a PIN for /checkLogin.cgi via vectors involving /portal_top.html to get full access to the device. NOTE: the vendor reportedly responded that this issue occurs when a customer keeps the default settings without using the countermeasures and best practices shown in the documentation
A remote attacker can bypass the System Manager Mode on the Canon MF210 and MF220 web interface without knowing the PIN for /login.html via vectors involving /portal_top.html to get full access to the device. NOTE: the vendor reportedly responded that this issue occurs when a customer keeps the default settings without using the countermeasures and best practices shown in the documentation
An issue was discovered on Canon LBP6650, LBP3370, LBP3460, and LBP7750C devices. It is possible to bypass the Administrator Mode authentication for /tlogin.cgi via vectors involving frame.cgi?page=DevStatus. NOTE: the vendor reportedly responded that this issue occurs when a customer keeps the default settings without using the countermeasures and best practices shown in the documentation
Cross-site request forgery (CSRF) vulnerability in the Remote UI on Canon PIXMA MG7500 printers allows remote attackers to hijack the authentication of administrators.
The default configuration of the administrative interface on the Canon MG3100, MG5300, MG6100, MP495, MX340, MX870, MX890, MX920, and MX922 printers does not require authentication, which allows remote attackers to modify the configuration by visiting the Advanced page. NOTE: the vendor has apparently responded by stating "for user convenience, the default setting does not require a password. However, if a user has a particular concern about third parties accessing the user's home printer, the default setting can be changed to add a password."
English/pages_MacUS/wls_set_content.html on the Canon MG3100, MG5300, MG6100, MP495, MX340, MX870, MX890, MX920, and MX922 printers shows the Wi-Fi PSK passphrase in cleartext, which allows physically proximate attackers to obtain sensitive information by reading the screen of an unattended workstation.
The Canon MG3100, MG5300, MG6100, MP495, MX340, MX870, MX890, MX920, and MX922 printers allow remote attackers to cause a denial of service (device hang) via a crafted LAN_TXT24 parameter to English/pages_MacUS/cgi_lan.cgi followed by a direct request to English/pages_MacUS/lan_set_content.html. NOTE: the vendor has apparently responded by stating "Canon believes that its printers will not have to deal with unauthorized access to the network from an external location as long as the printers are used in a secured environment."
The FTP print feature in multiple Canon printers, including imageRUNNER and imagePRESS, allow remote attackers to use the server as an inadvertent proxy via a modified PORT command, aka FTP bounce.
Cross-site scripting (XSS) vulnerability in the management interface in Canon Network Camera Server VB100 and VB101 with firmware 3.0 R69 and earlier, and VB150 with firmware 1.1 R39 and earlier, allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.
Microsoft Internet Explorer allows remote attackers to cause a denial of service (crash) via an IFRAME with a certain XML file and XSL stylesheet that triggers a crash in mshtml.dll when a refresh is called, probably a null pointer dereference.
