Security readout for executives and security teams
Plain-English summary
CVE-2026-1506 affects D-Link DIR-615 version 4.10 routers. A flaw in the MAC filter configuration page can let a remote attacker with high privileges inject operating system commands. Public exploit information exists. The source says the affected product is no longer supported, so replacement or isolation should be prioritized.
Executive priority
Treat as high priority where DIR-615 4.10 is present. The device is reportedly unsupported, the bug can affect full router integrity, and public exploit information exists. Prioritize discovery, management-plane isolation, and replacement planning.
Technical view
The issue is OS command injection in /adv_mac_filter.php, in the MAC Filter Configuration component. Manipulation of the mac argument can trigger command execution. CVSS v4.0 score is 8.6 with network attack vector, low complexity, no user interaction, and high required privileges. CWE mappings include CWE-77 and CWE-78.
Likely exposure
Exposure is likely limited to D-Link DIR-615 devices running firmware/version 4.10, especially if administrative router interfaces are reachable over untrusted networks. High privileges are required, but compromise of admin credentials or sessions could make the flaw usable.
Exploitation context
The vulnerability is remotely reachable and public exploit material is referenced. However, it is not listed as KEV in the provided data, and no cited source confirms active exploitation in the wild. Required privileges are high, reducing but not removing risk.
Researcher notes
Evidence identifies the affected endpoint, parameter, component, privileges, and CVSS vector, but not a vendor patch. Do not assume other DIR-615 versions are affected from this bundle alone. The public exploit reference should be handled carefully without reproducing offensive details.
Mitigation direction
- Identify any D-Link DIR-615 version 4.10 devices in the environment.
- Remove administrative interfaces from internet or untrusted network exposure.
- Restrict router administration to trusted management networks and accounts.
- Check D-Link guidance for any available product-specific advisory or replacement direction.
- Plan replacement because sources state the affected product is no longer supported.
Validation and detection
- Inventory routers by model and firmware version.
- Confirm whether any DIR-615 4.10 devices are deployed.
- Review whether /adv_mac_filter.php is reachable from untrusted networks.
- Check administrative access controls and account hygiene for affected devices.
- Monitor vendor and vulnerability databases for updated remediation information.
