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

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 2026-10-26.

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

1. Immediately disable remote management interfaces on ADSLR NBR1005GPEV2 routers to prevent external exploitation. 2. Implement strict network segmentation to isolate vulnerable routers from critical internal systems and sensitive data. 3. Monitor network traffic for unusual commands or patterns indicative of exploitation attempts targeting /send_order.cgi or the mac parameter. 4. Replace affected devices with alternative hardware from vendors with active security support if feasible. 5. Employ intrusion detection/prevention systems (IDS/IPS) tuned to detect command injection attempts specific to this vulnerability. 6. Restrict administrative access to the routers to trusted internal IP addresses only. 7. Regularly audit router configurations and firmware versions to identify and remediate vulnerable devices. 8. Engage with ADSLR or third-party security communities for any emerging patches or workarounds. 9. Educate network administrators about this vulnerability and encourage vigilance for signs of compromise. 10. Consider deploying network-level application firewalls to filter malicious payloads targeting CGI endpoints.

Description

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

Impact

For European organizations, this vulnerability poses a risk of unauthorized remote command execution on affected ADSLR NBR1005GPEV2 routers, potentially leading to device compromise, network infiltration, or denial of service. Compromised routers can be leveraged to intercept or manipulate network traffic, launch further attacks within internal networks, or disrupt connectivity critical for business operations. Given the router’s role as a network gateway, exploitation could undermine confidentiality and integrity of communications, especially in environments lacking additional network segmentation or monitoring. The medium CVSS score reflects limited but meaningful impact, as the vulnerability requires low privileges but no authentication, increasing exposure. Organizations in sectors with stringent security requirements, such as finance, healthcare, or critical infrastructure, may face elevated risks if these devices are deployed without compensating controls. The lack of vendor patching prolongs exposure, emphasizing the need for proactive defense measures.

Summary

CVE-2025-13799 identifies a command injection vulnerability in the ADSLR NBR1005GPEV2 router firmware version 250814-r037c. The vulnerability resides in the ap_macfilter_del function of the /send_order.cgi endpoint, where the mac parameter is insufficiently sanitized, allowing an attacker to inject arbitrary OS commands. This flaw can be exploited remotely over the network without requiring authentication or user interaction, making it accessible to unauthenticated attackers. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:L - low privileges), no user interaction (UI:N), and low impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). The lack of vendor remediation increases the risk of exploitation in the wild, potentially allowing attackers to execute arbitrary commands on affected devices, leading to device takeover, network pivoting, or disruption of network services. The affected product is a specific router model commonly used in small to medium business or residential environments, which may serve as a gateway to internal networks. The absence of patches necessitates alternative mitigation strategies to protect networks relying on this hardware.
