CVE-2026-71949: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in D-Link Corporation DWR-M961
D-Link DWR-M961 devices with hardware version C1 and firmware version before 1.1.5_C1_202607071108 contain a command injection vulnerability in the /boafrm/formUSSDSetup interface. A remote attacker can inject arbitrary malicious commands into the ussdValue and selectMenuValue fields, resulting in command execution with root privileges.
AI Analysis
Technical Summary
The vulnerability CVE-2026-71949 affects D-Link DWR-M961 devices (hardware version C1) running firmware versions prior to 1.1.5_C1_202607071108. It is an OS command injection flaw in the /boafrm/formUSSDSetup interface, where unsanitized input in the ussdValue and selectMenuValue parameters allows remote attackers to execute arbitrary commands with root privileges. The CVSS 4.0 base score is 9.3, indicating critical severity with network attack vector, no privileges or user interaction required, and high impacts on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation results in remote command execution with root privileges on affected devices, potentially allowing full control over the device and compromise of confidentiality, integrity, and availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround is currently documented. Users should monitor D-Link communications for firmware updates addressing this vulnerability.
