Summary

CVE-2025-13799 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.

A command injection vulnerability exists in the ADSLR NBR1005GPEV2 firmware version 250814-r037c, specifically in the ap_macfilter_del function of the /send_order.cgi endpoint. The flaw arises from improper handling of the mac argument, which can be manipulated to execute arbitrary commands. The issue is tracked under CWE-74 and CWE-77 and carries a low CVSS 4.0 score of 2.1, reflecting that it requires an authenticated remote attacker.

An authenticated attacker with network access can supply a crafted mac parameter to the affected CGI script and achieve command execution on the device. Public exploit code has been released, enabling potential remote compromise of the router without vendor interaction.

The vendor was notified prior to disclosure but provided no response or patch. Public references consist primarily of vulnerability database entries that document the issue and the submitted proof-of-concept.

EPSS for the CVE rose from a low baseline to a peak of 0.0141 on 2025-12-11 before receding to the current value of 0.0027, indicating a temporary increase in exploitation interest after public disclosure.
