Canon R-ADV C3325 Default Login Scanner

The Canon R-ADV C3325 is a multifunctional office printer specifically designed for businesses that require high-quality print, copy, scan, and fax capabilities. It is typically used in corporate and small business environments to manage document workflows efficiently. The printer is often deployed in departments where volume document handling is crucial, emphasizing ease of use, reliability, and security. Canon, a leading technology company, manufactures this model to enhance office productivity with advanced features. Its flexible workflow procedures allow integration with various industry-standard solutions, serving multipurpose roles in modern office settings. Besides its primary functions, the device is also utilized for network connectivity and mobile printing, making it versatile for diverse business needs.

The default login vulnerability detected by the scanner involves the use of preset credentials that come with the Canon R-ADV C3325. Devices shipped with a default username and password may not be changed by administrators during initial setup. This practice leaves the device susceptible to unauthorized access if network security policies are not enforced. Attackers could exploit default credentials to gain unauthorized access to the administrative portal of the machine. A threat actor with access to the default login could change security settings or perform administrative tasks without legitimate authorization. This vulnerability primarily occurs due to the oversight of securing administration interfaces and changing default configurations on deployment.

The vulnerability specifically targets the Canon R-ADV C3325 using HTTP requests to check for default login credentials. The endpoint vulnerable is typically at the login page where administrators log into the web interface. The parameters 'uri', 'user_type_generic', 'deptid', and 'password' are utilized in the POST request to authenticate. The scanner makes use of known default username and password combinations to try and access the system. It matches responses containing certain phrases that indicate a successful login, such as "Log Out" or "Remote UI : Portal". The vulnerability relies on specific status codes and webpage content to ascertain if default credentials are still in use.

If malicious agents successfully exploit this vulnerability, they could manipulate key functions of the Canon R-ADV C3325. Unauthorized access could lead to changes in secure settings, downloading of sensitive documents, or even introducing malicious firmware. The organization's data integrity and confidentiality could be compromised, leading to potential information leakage or data theft. Access to the printer network might also provide indirect access to other connected systems, escalating the security breach beyond local exploitation. Therefore, neglect in sanitizing default settings draws significant risk concerning operational control and data protection.
