CVE-2026-1506
Published: 28 January 2026
Summary
CVE-2026-1506 is a high-severity Command Injection (CWE-77) vulnerability in Dlink Dir-615 Firmware. Its CVSS base score is 7.3 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 33.5th percentile by exploit likelihood (below the median); 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 SA-22 (Unsupported System Components) and SI-10 (Information Input Validation).
Deeper analysis
CVE-2026-1506 is an OS command injection vulnerability (CWE-77, CWE-78) affecting the D-Link DIR-615 router on firmware version 4.10. The flaw exists in an unknown function of the /adv_mac_filter.php file within the MAC Filter Configuration component, triggered by manipulation of the 'mac' argument. It carries a CVSS v3.1 base score of 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H).
The vulnerability enables remote exploitation by attackers possessing high privileges, with low complexity and no user interaction required. Successful attacks allow arbitrary OS command execution, resulting in high impacts to confidentiality, integrity, and availability.
Advisories note that the exploit has been publicly disclosed and is available for use, as detailed in references such as VulDB entries and a dedicated Notion page. The vulnerability exclusively impacts products no longer supported by D-Link, with no patches available from the maintainer; the official D-Link site provides general product information but no specific remediation.
In context, this issue highlights risks in end-of-life embedded devices, where public exploit availability increases the likelihood of targeted attacks on exposed routers.

Directly requires validation and sanitization of the 'mac' input parameter in /adv_mac_filter.php to block OS command injection.
Mandates replacement or additional mitigations for the DIR-615, which is explicitly unsupported with no patches available.
Restricts the high-privilege accounts that can reach the vulnerable MAC Filter Configuration page, reducing the attack surface.
