However, an attacker would have to convince the victim to open the malicious file.\n\nUpon completion of this investigation, Microsoft will take the appropriate action to help protect our customers. This might include providing a security update through our monthly release process or providing an out-of-cycle security update, depending on customer needs.\n\nPlease see the Microsoft Threat Intelligence  Blog https://aka.ms/Storm-0978  Entry for important information about steps you can take to protect your system from this vulnerability.\n\nThis CVE will be updated with new information and links to security updates when they become available.","status":"published","published":"2023-07-11T21:30:58Z","modified":"2025-10-22T00:33:52Z","cvss":[{"version":"3.1","score":0,"vector":"CVSS:3.1/AV:P/AC:H/PR:H/UI:R/S:U/C:N/I:N/A:N","level":"none"}],"cwes":["CWE-362"],"updated_at":"2026-11-02T15:04:08.734574Z"}],"kev":[{"id":"CVE-2023-36884","title":"Microsoft Windows Search Remote Code Execution Vulnerability","description":"Microsoft Windows Search contains an unspecified vulnerability that could allow an attacker to evade Mark of the Web (MOTW) defenses via a specially crafted malicious file, leading to remote code execution.","cwes":["CWE-362"],"kev":{"date_added":"2023-07-17","due_date":"2023-08-29","required_action":"Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.","known_ransomware_use":"Known"},"updated_at":"2026-11-02T17:00:16.234141Z"}],"nvd":[{"id":"CVE-2023-36884","description":"Windows Search Remote Code Execution Vulnerability","status":"published","published":"2023-07-11T19:15:09.623Z","modified":"2026-08-10T16:18:30.637Z","cvss":[{"version":"3.1","score":7.5,"vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","level":"high","assessor":"secondary"},{"version":"3.1","score":7.5,"vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","level":"high","assessor":"secondary"}],"cwes":["CWE-362"],"updated_at":"2026-11-02T14:08:15.91037Z"}]}}
