CVE-2026-1448
Published: 27 January 2026
Summary
CVE-2026-1448 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 in the top 31.2% of CVEs by exploit likelihood; 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-2026-1448 is an OS command injection vulnerability affecting D-Link DIR-615 routers running firmware versions up to 4.10. The issue resides in an unknown function within the /wiz_policy_3_machine.php file of the Web Management Interface, where manipulation of the 'ipaddr' argument enables command execution. Associated with CWE-77 (Command Injection) and CWE-78 (OS Command Injection), 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) and was published on January 27, 2026.
Attackers with high privileges (PR:H) can exploit this vulnerability remotely over the network with low complexity. Successful exploitation allows arbitrary OS command injection, potentially granting high-impact confidentiality, integrity, and availability compromises, such as full system takeover on the affected router.
The vulnerability impacts products no longer supported by D-Link, precluding official patches or updates. Relevant advisories from sources like VulDB note the public availability of exploits, urging immediate isolation or replacement of affected devices; the manufacturer's site (dlink.com) provides no specific mitigation details for this EOL hardware.

Directly enforces validation of the ipaddr argument in wiz_policy_3_machine.php to block OS command injection payloads.
Mandates replacement or isolation of the explicitly unsupported EOL D-Link DIR-615 firmware that can never receive a patch.
Limits the high-privilege (PR:H) web-interface account required to reach the vulnerable function, reducing exploitability and blast radius.
