Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 18.6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and AC-6 (Least Privilege).
Deeper analysis
CVE-2026-1624 is a command injection vulnerability in the D-Link DWR-M961 router running firmware version 1.1.47. The issue affects an unknown function within the file /boafrm/formLtefotaUpgradeFibocom, where manipulation of the fota_url argument enables arbitrary command execution. Classified under CWE-74 and CWE-77, it carries 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) and was published on 2026-01-29.
The vulnerability can be exploited remotely by an attacker with low privileges, such as an authenticated user, requiring no user interaction and low complexity. Successful exploitation allows limited impacts on confidentiality, integrity, and availability, potentially enabling command execution on the device.
