CVE-2022-23227 (GCVE-0-2022-23227)

Vulnerability from cvelistv5 – Published: 2022-01-14 17:13 – Updated: 2025-10-21 23:15

Summary

NUUO NVRmini2 through 3.11 allows an unauthenticated attacker to upload an encrypted TAR archive, which can be abused to add arbitrary users because of the lack of handle_import_user.php authentication. When combined with another flaw (CVE-2011-5325), it is possible to overwrite arbitrary files under the web root and achieve code execution as root.

Severity

9.8 (Critical)
