AI Analysis
Technical Summary
CVE-2026-11339 is a command injection vulnerability affecting D-Link DWR-M920 devices running firmware versions up to 1.1.50. The vulnerability arises from improper sanitization of the ussdValue parameter in the sub_41CF20 function of the /boafrm/formUSSDSetup file, enabling remote attackers to execute arbitrary commands on the device. The exploit is publicly available, but no official patch or remediation level has been disclosed by the vendor as of the publication date.
Potential Impact
Successful exploitation allows remote attackers to execute arbitrary commands on affected D-Link DWR-M920 devices, potentially compromising device integrity and confidentiality. The vulnerability has a CVSS 4.0 base score of 5.3 (medium severity), reflecting the network attack vector, low attack complexity, no user interaction required, and limited scope and impact on confidentiality, integrity, and availability.
Mitigation Recommendations
No official patch or remediation guidance has been published by the vendor. Users should monitor the vendor's advisories for updates. Until a fix is available, restricting remote access to the device management interface and disabling USSD functionality if possible may reduce exposure.
