Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: High: There is a total loss of confidentiality, resulting in all information within the Vulnerable System being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact. For example, an attacker steals the administrator's password, or private encryption keys of a web server.
Vulnerable system integrity: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-25.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

Upgrade Davantis DFUSION to 6.186.1.

AI-suggested

1. Immediate mitigation should focus on restricting network access to the vulnerable endpoints by implementing firewall rules or network segmentation to limit access to trusted internal users only. 2. Monitor and audit access logs for unusual or unauthorized requests to the /alarms/<ALARM_ID>/<MEDIA> endpoint to detect potential exploitation attempts. 3. Coordinate with Davantis to obtain and apply official patches or updates as soon as version 6.186.1 or later becomes available, as this will address the missing authorization checks. 4. If patches are not yet available, consider deploying web application firewalls (WAFs) with custom rules to block unauthorized access patterns targeting the media retrieval endpoints. 5. Conduct a thorough review of all access control configurations in the DFUSION system to ensure proper authorization enforcement on all sensitive resources. 6. Educate security and IT teams about the vulnerability and the importance of rapid response to suspicious activity related to surveillance media. 7. Evaluate alternative or supplementary surveillance solutions with robust access controls as a longer-term risk reduction strategy. 8. Ensure compliance teams are involved to assess privacy impact and prepare for potential incident response related to data exposure.

Description

CVE-2025-41016 is a high-severity vulnerability in Davantis DFUSION versions prior to 6.186.1 that allows unauthenticated attackers to access sensitive media files such as snapshots and videos related to alarm events. The flaw stems from missing authorization checks on the endpoint /alarms/<ALARM_ID>/<MEDIA>, enabling unauthorized extraction of security camera footage triggered by alerts. Exploitation requires no authentication or user interaction and can lead to significant confidentiality breaches. Although no known exploits are reported in the wild yet, the vulnerability's ease of exploitation and the sensitivity of the data involved make it a critical concern for organizations using this product. European organizations relying on Davantis DFUSION for security monitoring are at risk of exposure of private surveillance footage, potentially impacting privacy compliance and operational security. Mitigation involves promptly updating to version 6.186.1 or later once available and implementing network-level access controls to restrict access to the vulnerable endpoints.

Impact

The primary impact of CVE-2025-41016 on European organizations is the unauthorized disclosure of sensitive surveillance media, which can compromise privacy and security. Organizations in sectors such as critical infrastructure, transportation, government facilities, and private enterprises using Davantis DFUSION for alarm-triggered video monitoring could have confidential footage exposed to attackers. This exposure risks violating GDPR and other privacy regulations, potentially leading to legal penalties and reputational damage. Additionally, attackers could use the extracted media to conduct further reconnaissance or plan physical or cyber attacks. The lack of authentication and user interaction requirements increases the likelihood of exploitation, especially if the vulnerable endpoints are accessible from external networks. The vulnerability could also undermine trust in security operations and cause operational disruptions if organizations need to disable affected systems temporarily. Given the high confidentiality impact and the critical nature of surveillance data, the threat is significant for European entities relying on this technology.

The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
Architecture and Design
Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries.
Architecture and Design
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records.
