Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

Directly prevents command injection by requiring validation and sanitization of the untrusted 'mac' argument in the ap_macfilter_add function of /send_order.cgi.

prevent

Mandates timely identification, reporting, and correction of the specific command injection flaw in ADSLR NBR1005GPEV2 firmware version 250814-r037c.

detect

Enables vulnerability scanning to identify unpatched ADSLR NBR1005GPEV2 devices affected by this publicly exploited CVE.

MITRE ATT&CK Enterprise TechniquesAI

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.
T1059.004 Unix Shell Execution
Adversaries may abuse Unix shell commands and scripts for execution.
Why these techniques?

Command injection vulnerability in web CGI script (/send_order.cgi) on network device enables exploitation of public-facing application (T1190) for arbitrary Unix shell command execution (T1059.004).

published and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Deeper analysisAI

CVE-2025-13798 is a command injection vulnerability in the ADSLR NBR1005GPEV2 device running firmware version 250814-r037c. The flaw resides in the ap_macfilter_add function within the /send_order.cgi script, where manipulation of the "mac" argument enables attackers to inject arbitrary commands. This issue corresponds to CWE-74 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-77 (Command Injection), with 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).

The vulnerability can be exploited remotely by an authenticated attacker with low privileges over the network, requiring no user interaction. Successful exploitation allows limited impacts on confidentiality, integrity, and availability, potentially enabling arbitrary command execution on the device.

Advisories from VulDB indicate that a public exploit is available and may be actively used, but the vendor was notified early without any response or patch release. References include VulDB entries (ctiid.333809, id.333809, submit.691841) and Notion pages detailing the report.

An exploit for this vulnerability has been published, increasing the risk of real-world exploitation on unpatched ADSLR NBR1005GPEV2 devices.
