Threat metrics

Exploit Maturity: POC

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: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
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: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact to the Vulnerable System.
Vulnerable system availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the Vulnerable System are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to 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.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

Exploitation evidence

Disclosed: evidence found.
CVE published 1 Dec 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: evidence found.

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), CVSS vector, 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 or the CVSS exploit maturity 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

Immediately identify and inventory all ADSLR NBR1005GPEV2 devices running firmware version 250814-r037c or earlier.
Disable remote management interfaces and any unnecessary services, especially those exposing /send_order.cgi endpoints.
Implement strict network segmentation to isolate vulnerable routers from critical systems and sensitive data.
Monitor network traffic for unusual commands or activity targeting the mac parameter or /send_order.cgi endpoint.
Employ intrusion detection/prevention systems (IDS/IPS) with signatures for known exploit patterns related to this vulnerability.
Restrict access to router management interfaces to trusted IP addresses only.
Regularly check for vendor updates or patches and apply them promptly once available.
Consider replacing vulnerable devices with alternative hardware if patches are not forthcoming.
Conduct security awareness training for network administrators to recognize signs of exploitation.
Maintain up-to-date backups of router configurations to enable rapid recovery if compromise occurs.

Description

A vulnerability was found in ADSLR NBR1005GPEV2 250814-r037c. This issue affects the function set_mesh_disconnect of the file /send_order.cgi. The manipulation of the argument mac results in command injection. It is possible to launch the attack remotely. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

For European organizations, exploitation of CVE-2025-13800 could lead to unauthorized command execution on vulnerable ADSLR NBR1005GPEV2 routers, resulting in device takeover, network disruption, or pivoting to internal systems. This could compromise confidentiality by exposing sensitive network traffic or credentials, integrity by altering device configurations or firmware, and availability by causing denial of service. Organizations relying on these routers for mesh networking or critical connectivity may experience operational outages or data breaches. The absence of vendor patches increases exposure duration, and public exploit availability raises the likelihood of targeted attacks. Industries with stringent regulatory requirements (e.g., finance, healthcare, critical infrastructure) could face compliance violations and reputational damage. The threat is amplified in environments with limited network segmentation or weak monitoring, enabling attackers to move laterally once inside the network. European entities with remote management enabled on these devices are particularly at risk due to the remote exploitability without authentication.
