CVE-2026-2959

### 1. Plain-Language Summary This vulnerability is a stack-based buffer overflow in the D-Link DWR-M960 router firmware. An attacker can remotely crash the device or potentially take control of it by sending a specially crafted malicious URL to the router’s web interface. ### 2. Who Is Affected - **Product**: D-Link DWR-M960 router - **Version**: Firmware version 1.01.07 - **Scope**: Any device running this specific firmware is vulnerable. Older/newer versions are not mentioned and should be checked against vendor advisories. ### 3. Attacker Impact An attacker exploiting this could: - **Execute arbitrary code**: Gain full control of the router (e.g., intercept traffic, launch attacks from the device). - **Cause denial of service**: Crash the device, disrupting network connectivity. - **Exploit remotely**: Attack requires no physical access—only network connectivity to the router’s web interface. ### 4. Recommended Remediation - **Patch Immediately**: Update the router to a firmware version **higher than 1.01.07** (check D-Link’s security advisories for patches). - **Mitigate if Unpatched**: - Disable remote management access to the router. - Restrict web interface access to trusted internal IPs only. - Block unsolicited inbound traffic to the router’s IP. - **Replace if Unsupported**: If no patch is available, decommission the device and replace it with a supported router. - **Monitor**: Verify updates via D-Link’s official channels (e.g., [D-Link Support](https://support.dlink.com)). > **Urgency Note**: The exploit is public (CVSS 8.8 HIGH). Prioritize patching or mitigating immediately to prevent compromise.
