Technical Summary
CVE-2026-5386 affects KMW KM-IP521 CCTV cameras, enabling an unauthenticated remote attacker to reset the administrator password to a known value without any authentication. This vulnerability is due to an unverified password change mechanism (CWE-620). The flaw allows full compromise of the device, including access to live camera feeds and configuration settings. The CVSS v3.1 base score is 9.1, reflecting high impact on confidentiality and integrity with no required privileges or user interaction. The affected version is 4.04.91.230307. No patch or official remediation has been disclosed by KMW as of the publication date.
Potential Impact
Successful exploitation results in complete takeover of the affected CCTV camera, allowing an attacker to view all camera feeds and modify device settings without any authentication. This compromises the confidentiality and integrity of surveillance data and device operation. Availability impact is not indicated. The vulnerability poses a critical risk to physical security monitoring relying on these devices.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict network access to the affected cameras to trusted management networks only and monitor for unauthorized access attempts. Avoid exposing these devices directly to untrusted networks. Follow vendor updates closely for patch availability.
