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

Attack Vector: Local: The vulnerable system is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or through terminal emulation (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., using social engineering techniques to trick a legitimate user into opening a malicious document).
Attack Complexity: High: The successful attack depends on the evasion or circumvention of security-enhancing techniques in place that would otherwise hinder the attack. These include: Evasion of exploit mitigation techniques, for example, circumvention of address space randomization (ASLR) or data execution prevention (DEP) must be performed for the attack to be successful; Obtaining target-specific secrets. The attacker must gather some target-specific secret before the attack can be successful. A secret is any piece of information that cannot be obtained through any amount of reconnaissance. To obtain the secret the attacker must perform additional attacks or break otherwise secure measures (e.g. knowledge of a secret key may be needed to break a crypto channel). This operation must be performed for each attacked target.
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: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the vulnerable system. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to 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 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 versions and upgrade to the latest patched firmware provided by the manufacturer. Since the vulnerability requires high privileges and local network access, organizations should also strengthen internal network segmentation to limit access to NVR devices only to authorized personnel and systems. Implement strict access controls and monitoring on the management interfaces of these devices. Employ network intrusion detection systems (NIDS) to detect anomalous activities targeting NVRs. Regularly audit device configurations to ensure no default or hard-coded credentials remain in use. Additionally, consider isolating surveillance networks from general corporate networks to reduce the attack surface. Organizations should also maintain an incident response plan that includes procedures for compromised surveillance equipment. Finally, coordinate with Hanwha Vision support channels to receive timely updates and advisories.

Description

Team ENVY, a Security Research TEAM has found a flaw that allows for a remote code execution on the NVR. The seed string for the encrypt key was hardcoding. The manufacturer has released patch firmware for the flaw, please refer to the manufacturer's report for details and workarounds.

Impact

For European organizations, this vulnerability poses a significant risk to the security and integrity of video surveillance infrastructure. NVRs like the Hanwha Vision XRN-420S are often deployed in critical infrastructure, corporate security, public safety, and government facilities. Successful exploitation could allow attackers to execute arbitrary code, potentially leading to unauthorized access to video feeds, tampering with recorded footage, or disrupting surveillance operations. This could undermine physical security measures and lead to data integrity issues. Given the medium severity and the requirement for high privileges and local access, the threat is more pronounced in environments where internal network security is weak or where attackers have already gained some level of network foothold. The lack of known exploits in the wild suggests limited immediate risk, but the presence of a patch indicates that proactive remediation is essential to prevent future exploitation. Additionally, the compromise of surveillance systems can have cascading effects on compliance with European data protection regulations such as GDPR, especially if video data is exposed or manipulated.

Summary

CVE-2024-41885 is a medium-severity vulnerability identified in the Hanwha Vision XRN-420S Network Video Recorder (NVR) devices, specifically affecting firmware versions 5.01.62 and earlier. The root cause of this vulnerability is the use of a hard-coded seed string for the encryption key, classified under CWE-547 (Use of Hard-coded, Security-relevant Constants). This design flaw allows an attacker with high privileges on the local network (as indicated by the CVSS vector AV:L and PR:H) to potentially execute remote code on the affected device without requiring user interaction. The vulnerability does not affect confidentiality or availability directly but impacts the integrity of the system, as it enables an attacker to manipulate the device's operation through code execution. The exploitation complexity is high due to the need for high privileges and local access, and no known exploits are currently reported in the wild. The manufacturer has released patched firmware to address this issue, although no direct patch links were provided in the source information. The vulnerability was publicly disclosed on December 24, 2024, and was reserved in July 2024. The CVSS 4.0 base score is 5.6, reflecting a medium severity level. The flaw arises because the encryption seed string is hard-coded, which can be reverse-engineered or discovered by attackers, allowing them to bypass encryption protections and execute arbitrary code remotely on the device. This vulnerability is critical to address in environments where these NVRs are deployed, especially in security-sensitive contexts.

Base weaknessOWASP Top 10 A02:2025: Security Misconfiguration (opens in a new tab)
The product uses hard-coded constants instead of symbolic names for security-critical values, which increases the likelihood of mistakes during code maintenance or security policy change.
Implementation
Avoid using hard-coded constants. Configuration files offer a more flexible solution.
