CVE-2025-41016 in DFUSION
Summary
by MITRE • 11/24/2025
Inadequate access control vulnerability in Davantis DFUSION v6.177.7, which allows unauthorised actors to extract images and videos related to alarm events through access to “/alarms/<ALARM_ID>/<MEDIA>”, where the “MEDIA” parameter can take the value of “snapshot” or “video.mp4”. These media files contain images recorded by security cameras in response to triggered alerts.

This vulnerability represents a critical access control flaw in Davantis DFUSION v6.177.7 that exposes security camera media assets to unauthorized parties. The issue stems from insufficient authorization checks within the application's media retrieval endpoint, specifically the "/alarms/<ALARM_ID>/<MEDIA>" path where the MEDIA parameter can be set to either "snapshot" or "video.mp4". This allows malicious actors to directly access security footage and images without proper authentication or privilege validation, fundamentally undermining the security model of the surveillance system.
The technical implementation of this vulnerability falls under CWE-284 which describes inadequate access control mechanisms. Attackers can exploit this weakness by constructing direct API requests to the vulnerable endpoint, bypassing normal authentication flows that should restrict access to security media files. The flaw essentially creates a backdoor through which any individual with knowledge of the system's URL structure can retrieve sensitive visual data from security cameras triggered by alarm events. This represents a fundamental failure in the principle of least privilege where access to security media should be strictly controlled based on user roles and permissions.
The operational impact of this vulnerability is severe for organizations relying on Davantis DFUSION for security monitoring. Unauthorized access to alarm-triggered media files could expose sensitive information about security incidents, potentially revealing system vulnerabilities, operational patterns, or even compromising ongoing investigations. The extracted snapshot and video.mp4 files contain critical evidence of security events that could be used for various malicious purposes including social engineering attacks, physical security planning by adversaries, or corporate espionage. Organizations using this software face potential regulatory compliance violations and increased risk of security breaches.
Mitigation strategies should focus on implementing robust access control measures at the application level, including proper authentication validation and authorization checks for all media retrieval endpoints. Organizations should immediately implement role-based access controls that restrict media file access to authorized personnel only, with logging and monitoring of all media access attempts. The system should enforce mandatory authentication for all requests to the /alarms/<ALARM_ID>/<MEDIA> endpoint and validate user permissions against the specific alarm event and media type being requested. Additionally, network-level firewalls should be configured to restrict access to these endpoints to trusted IP addresses and implement rate limiting to prevent automated enumeration attacks. Regular security assessments and penetration testing should be conducted to identify similar access control vulnerabilities across the entire security infrastructure, aligning with ATT&CK framework techniques for privilege escalation and credential access.
