Summary

CVE-2025-13800 is a low-severity Injection (CWE-74) vulnerability in Adslr B-Qe2W401 Firmware. Its CVSS base score is 2.1 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 5% 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 map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

The vulnerability is a command injection flaw in the ADSLR NBR1005GPEV2 firmware version 250814-r037c. It resides in the set_mesh_disconnect function of the /send_order.cgi endpoint, where unsanitized input to the mac argument is passed to an operating system command. The issue is tracked under CWE-74 and CWE-77 and carries a CVSS 4.0 score of 2.1.

An authenticated remote attacker can supply a crafted mac value to execute arbitrary commands on the device. Because the attack requires only low privileges and no user interaction, an adversary who has obtained valid credentials or who already controls a low-privileged account can achieve limited code execution, data modification, or service disruption on the affected router.

Public references on Vuldb document the disclosure timeline and note that the vendor was contacted prior to publication but provided no response or patch. No official mitigation guidance or firmware update has been issued.

The exploit code has been released publicly. The associated EPSS score rose from a baseline near 0.0027 to a peak of 0.0141 on 11 December 2025 before receding, indicating a measurable but short-lived increase in exploitation interest after the CVE became public.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover command-construction flaws before deployment.

SI-10 directly requires validation of information inputs to reject malformed or special-element content before it reaches downstream parsers.

Secure engineering principles include proper neutralization and safe command construction practices.
