Summary

CVE-2025-13800 is a medium-severity Injection (CWE-74) vulnerability in Adslr B-Qe2W401 Firmware. Its CVSS base score is 6.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Unix Shell (T1059.004); ranked in the top 49.9% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Threat & Defense at a Glance

What attackers do: exploitation maps to Unix Shell (T1059.004) and 2 other techniques. What defenders deploy: see the NIST 800-53 controls recommended below.
Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

SI-10 mandates information input validation and error handling at interfaces, directly preventing command injection via the unvalidated 'mac' argument in /send_order.cgi.

prevent

SI-2 requires timely flaw remediation, addressing the unpatched command injection vulnerability in the ADSLR NBR1005GPEV2 firmware.

prevent

AC-6 enforces least privilege, limiting low-privilege (PR:L) access to the vulnerable set_mesh_disconnect function and reducing exploitation potential.

MITRE ATT&CK Enterprise TechniquesAI

T1059.004 Unix Shell Execution
Adversaries may abuse Unix shell commands and scripts for execution.
T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1202 Indirect Command Execution Stealth
Adversaries may abuse utilities that allow for command execution to bypass security restrictions that limit the use of command-line interpreters.
Why these techniques?

The command injection vulnerability (CWE-77) in the web CGI script (/send_order.cgi) enables remote exploitation of a public-facing application (T1190), leading to arbitrary Unix shell command execution (T1059.004) via indirect command execution (T1202).

NVD 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.

Deeper analysisAI

CVE-2025-13800 is a command injection vulnerability affecting the ADSLR NBR1005GPEV2 device on firmware version 250814-r037c. The flaw exists in the set_mesh_disconnect function of the /send_order.cgi file, where manipulation of the 'mac' argument enables command injection. Published on 2025-12-01, it carries a CVSS v3.1 base score of 6.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L) and is linked to CWE-74 and CWE-77.

An attacker with low privileges can exploit this vulnerability remotely over the network with low complexity and no user interaction required. Successful exploitation allows limited impacts, including partial disclosure of sensitive information, modification of data, and denial of service through arbitrary command execution.

VulDB advisories detail the issue and note that a public exploit is available, increasing the risk of active use. The vendor was contacted early for disclosure but provided no response, and no patches or official mitigations have been issued. Security practitioners should review references such as https://vuldb.com/?ctiid.333811, https://vuldb.com/?id.333811, and https://vuldb.com/?submit.691942 for further details and consider network segmentation or access controls until remediation is available.
