{"id":"CVE-2026-14551","state":"PUBLISHED","title":"Local Privilege Escalation in servereye client (sensorhub)","description":"The servereye client (also known as sensorhub, technically ClientAgentContainerService) versions 20.15 and earlier are vulnerable to Local Privilege Escalation. The high-privileged service SE3Recovery (EmergencyRecoveryService.exe), running as SYSTEM, periodically monitors the directory %ProgramData%\\ServerEye3\\update\\ for a trigger file named \"update_available\". Due to insufficient access restrictions on this directory, a local standard user can create the trigger file and provide a path to a directory containing malicious JSON instructions. The service subsequently executes the utility UpdaterAction.exe with SYSTEM privileges, which parses the instructions and performs an unvalidated file copy from a user-controlled source to a protected system destination (e.g., overwriting a service binary). This leads to full system compromise as the service automatically restarts the overwritten binary with SYSTEM privileges.","publishedAt":"2026-07-22T09:42:34.205Z","updatedAt":"2026-07-22T12:41:00.539Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","source":"NCSC.ch"},"assigner":"NCSC.ch","products":["servereye GmbH servereye Windows Agent (Sensorhub)"],"affected":[{"vendor":"servereye GmbH","product":"servereye Windows Agent (Sensorhub)","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"20.15","versionType":"custom"},{"version":"20.16","status":"unaffected","versionType":"custom"}],"platforms":["Windows"]}],"references":["https://www.servereye.de/security-bulletins/2026-001/"],"weaknesses":["CWE-379","CWE-269","CWE-73"],"ingestedAt":"2026-10-29T20:11:00.674Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/14xxx/CVE-2026-14551.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-14551","state":"PUBLISHED","datePublished":"2026-07-22T09:42:34.205Z","dateUpdated":"2026-07-22T12:41:00.539Z","assignerShortName":"NCSC.ch","assignerOrgId":"455daabc-a392-441d-aa46-37d35189897c","dateReserved":"2026-07-03T08:49:30.333Z"},"containers":{"cna":{"title":"Local Privilege Escalation in servereye client (sensorhub)","descriptions":[{"lang":"en","value":"The servereye client (also known as sensorhub, technically ClientAgentContainerService) versions 20.15 and earlier are vulnerable to Local Privilege Escalation.
