EasyCVR Information Disclosure Scanner

EasyCVR video management platform is a robust solution used by organizations for storing, managing, and retrieving video surveillance data. It is widely utilized in industries that require extensive security setups such as government facilities, retail chains, and municipal infrastructures. The platform offers core functionalities like live video monitoring, playback support, and intelligent video analysis. Its integration capabilities allow it to connect with numerous cameras and sensors, enhancing surveillance efficiency. EasyCVR's interface provides users with easy access to video feeds and logs, serving as a crucial tool for security personnel and operations teams. Its primary aim is to ensure seamless video management, critical for security and operational continuity.

The Information Disclosure vulnerability in the EasyCVR video management platform can lead to unauthorized exposure of sensitive data. It occurs when unjustly exposed configurations or controls allow outsiders to gain access to restricted information. This vulnerability often results in leakage of user data, enabling malicious parties to obtain details like usernames, roles, and potentially hashed passwords. Such discrepancies not only endanger user privacy but can also compromise the entire video management ecosystem. Continuous monitoring for inadvertent information exposure is critical to mitigate associated risks. Affected users must consider stringent controls over the announced data to protect against data breaches.

The technical details of the vulnerability involve an unsecured API endpoint exposed to unauthorized users. The endpoint allows repeated GET requests which return data about users, including roles and passwords, without proper authentication. Such endpoints, when not properly secured, pose a significant risk as they can be exploited by attackers to harvest user data. The specific API endpoint `/api/v1/userlist` is vulnerable due to the lack of authentication checks, permitting data exposure publicly. This lack of security considerations makes it easier for attackers to map out user hierarchies and their respective roles, leading to targeted attacks. It is crucial to employ stringent authentication mechanisms on such endpoints to prevent data compromise.

If successfully exploited, this vulnerability could lead to severe consequences, including unauthorized data harvesting and identity theft. Information disclosed through the API could be used by attackers to infiltrate other connected systems, assuming logged user roles. Such actions can enable malicious actors to conduct fraudulent activities, escalate privileges, or execute malicious code within the system. It increases the risk of targeted phishing attacks against users whose data has been exposed, potentially leading to financial or reputational damage. Security breach incidents resulting from this vulnerability can incur high costs pertaining to data restoration and legal compliance.
