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: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the Vulnerable System.
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.

AI-suggested

To mitigate CVE-2026-0853, European organizations should implement network segmentation to isolate NVR devices from untrusted networks and restrict access to management interfaces. Employ firewall rules or access control lists (ACLs) to limit connections to the debug page only from trusted administrative hosts. If possible, disable or restrict the debug interface on the AP-RM864P devices to prevent unauthorized access. Regularly audit device configurations and network traffic logs to detect any unauthorized access attempts or unusual activity targeting the debug page. Apply any available firmware updates or patches from A-Plus Video Technologies as they become available, even though none are currently published. Consider deploying intrusion detection/prevention systems (IDS/IPS) tuned to detect reconnaissance or exploitation attempts against these devices. Finally, maintain an asset inventory to identify all deployed AP-RM864P devices and assess their exposure to external networks, prioritizing remediation efforts accordingly.

Description

CVE-2026-0853 is a medium severity vulnerability affecting the A-Plus Video Technologies AP-RM864P NVR devices. It allows unauthenticated remote attackers to access a debug page, exposing sensitive device status information. The vulnerability does not require user interaction or authentication and can be exploited over the network with low complexity. Although no known exploits are currently reported in the wild, the exposure of sensitive system information could aid attackers in further targeting the device or network. European organizations using these NVR models may face risks related to confidentiality breaches and potential reconnaissance by attackers. Mitigation involves restricting network access to the device, disabling debug interfaces if possible, and monitoring network traffic for unauthorized access attempts. Countries with higher adoption of A-Plus Video Technologies products or critical infrastructure relying on these NVRs are more likely to be affected. Given the CVSS score of 6.9, the vulnerability is considered medium severity but warrants prompt attention to prevent escalation.

Impact

For European organizations, this vulnerability poses a risk primarily to confidentiality. Exposure of sensitive device status information can provide attackers with valuable intelligence to plan further attacks, such as identifying firmware versions, network configurations, or security settings. This reconnaissance capability can lead to more sophisticated exploitation attempts, including privilege escalation or denial of service. Organizations relying on these NVRs for video surveillance, especially in critical infrastructure sectors like transportation, energy, or government facilities, may face increased risk of targeted attacks. The lack of authentication and ease of remote exploitation increase the attack surface, particularly for devices exposed to untrusted networks or the internet. While the vulnerability does not directly impact device integrity or availability, the information disclosure can indirectly facilitate attacks that compromise these aspects. Additionally, regulatory compliance frameworks in Europe, such as GDPR, may consider unauthorized exposure of system information a data protection concern, potentially leading to legal and reputational consequences.

Summary

CVE-2026-0853 identifies a vulnerability in the A-Plus Video Technologies AP-RM864P network video recorder (NVR) devices. The flaw is categorized under CWE-497, which involves the exposure of sensitive system information to unauthorized entities. Specifically, the vulnerability allows unauthenticated remote attackers to access the device's debug page, which is not properly secured. This debug page reveals device status information that could include configuration details, operational status, or other sensitive metadata. The vulnerability has a CVSS 4.0 base score of 6.9, indicating medium severity, with attack vector being network (AV:N), no required privileges (PR:N), no user interaction (UI:N), and no authentication (AT:N). The impact is limited to information disclosure (VC:L), with no direct impact on integrity or availability. The vulnerability is exploitable remotely without authentication, making it accessible to attackers scanning for vulnerable devices. Although no patches or exploits are currently documented, the exposure of debug information can facilitate further attacks such as targeted exploitation or lateral movement within a network. The affected product is the AP-RM864P model, with no specific affected versions detailed beyond version '0', suggesting the vulnerability may be present in initial or all firmware versions. The vulnerability was published on January 12, 2026, by the Taiwan Computer Emergency Response Team (twcert).
