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: High: The attacker requires privileges that provide significant (e.g., administrative) control over the vulnerable system allowing full access to the vulnerable system’s settings and files.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: None: There is no loss of confidentiality within the Vulnerable System.
Vulnerable system integrity: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system availability: High: There is a total loss of availability, resulting in the attacker being able to fully deny access to resources in the Vulnerable System; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the Vulnerable System (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).
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.

Exploitation evidence

Disclosed: evidence found.
CVE published 24 Dec 2024
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

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 26 Oct 2026.

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

AI-suggested

European organizations using Hanwha Vision XRN-420S devices should immediately verify their firmware version and upgrade to the latest patched firmware provided by the manufacturer to remediate this vulnerability. Network segmentation should be implemented to isolate NVR devices from untrusted networks, minimizing exposure to remote attacks. Deploying strict firewall rules to restrict access to the NVR management interfaces only to authorized personnel and trusted IP addresses can reduce attack surface. Monitoring network traffic for unusual URL parameter patterns or repeated reboot events can help detect attempted exploitation. Additionally, organizations should review and harden device configurations, disable any unnecessary services or remote management features, and ensure strong authentication mechanisms where applicable. Regular vulnerability assessments and penetration testing focused on IoT and surveillance infrastructure will help identify similar weaknesses proactively. Finally, maintaining an inventory of all deployed IoT devices and their firmware versions is critical for timely patch management.

Description

Team ENVY, a Security Research TEAM has found a flaw that allows for a remote code execution on the NVR. An attacker could inject malformed data into url input parameters to reboot the NVR. The manufacturer has released patch firmware for the flaw, please refer to the manufacturer's report for details and workarounds.

Impact

For European organizations, the impact of CVE-2024-41886 can be substantial, particularly for entities relying on Hanwha Vision XRN-420S NVRs for video surveillance and security monitoring. Successful exploitation can lead to denial of service through forced reboots, disrupting continuous video recording and surveillance operations. This can result in gaps in security monitoring, loss of critical video evidence, and potential exposure to physical security risks. Organizations in sectors such as critical infrastructure, transportation, government facilities, and large enterprises that depend on video surveillance for safety and compliance may face operational disruptions and increased risk of security incidents. Additionally, repeated forced reboots could degrade device hardware over time, leading to increased maintenance costs and downtime. Although the vulnerability does not appear to allow full system compromise or data exfiltration, the availability impact alone can have serious consequences for security posture and incident response capabilities.
