Risk Analysis

D-Link DAR-7000 gateways are vulnerable to SQL injection via the editrole.php component, which can lead to sensitive information disclosure and arbitrary code execution. This is a critical remote vulnerability.

No public exploit is currently known, and the vulnerability is not in the KEV catalog. It is remotely exploitable.

Recommended Action

Update the device firmware to a version beyond 31R02B1413C and restrict access to the management interface.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2023-42406 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.

From a weakness classification perspective (CWE-89): SQL injection vulnerabilities allow attackers to manipulate database queries, potentially exposing or modifying sensitive data.
