Intelbras DVR Unauthenticated Access Scanner

Intelbras DVR is widely used for video surveillance solutions in various environments such as homes, businesses, and public spaces. It is primarily utilized by security professionals, facility managers, and systems integrators to ensure constant monitoring and recording of video footage. The DVR systems are valued for their reliability, ease of use, and integration capabilities with existing security infrastructure. Intelbras DVR products are often chosen for their robustness, which aids in preventing unauthorized access to closed-circuit television (CCTV) systems. The devices play a crucial role in security operations by providing real-time video feeds and archival footage for review. Given their role in security, proper functioning and protection against vulnerabilities are critical.

Unauthenticated Access is a significant vulnerability that can allow unauthorized users to gain access to sensitive information or restricted functionalities within a system. Such vulnerabilities arise when authentication processes are insufficiently implemented, often due to misconfigurations or lack of stringent security measures. Exploitation of this vulnerability could result in unauthorized disclosure of sensitive information, manipulation of system settings, or unauthorized actions within the network. Identifying and addressing Unauthenticated Access is crucial in maintaining the security posture of the system and preventing potential information breaches. Continuous monitoring and timely updates of authentication mechanisms are essential to mitigate such vulnerabilities.

The vulnerability in Intelbras DVR manifests through an unrestricted access point, specifically via the HTTP GET request to the /cap.js endpoint. This endpoint is essential for privileged operations, providing access to parameters like "var talkTypes" and "var userInfo" that should be secured. When improperly protected, this endpoint can be exploited to reveal sensitive information, affecting the overall security of the DVR system. Proper authentication checks are not enforced during the access of this endpoint, allowing malicious actors to retrieve sensitive data without authorization. Securing such endpoints is vital to strengthen the authentication measures and limit access to authorized personnel only. Immediate remediation is necessary to prevent exploitation through this uncontrolled access point.

Exploitation of the Unauthenticated Access vulnerability in Intelbras DVR systems could lead to several potential consequences. Malicious actors might gain unauthorized access to sensitive video footage, impacting privacy and security. There is also the risk of unauthorized changes to device configurations, potentially disrupting video surveillance activities. Additionally, attackers could exploit the vulnerability to further infiltrate the network, escalating privileges, or obtaining further unauthorized access to network resources. These effects can undermine the effectiveness of surveillance operations, posing risks to the safety and privacy of individuals and properties involved.
