NUUO NVRmini2 Devices Missing Authentication Vulnerability
Exploited in the wild
This vulnerability is on a Known Exploited Vulnerabilities catalogue, added 2024-12-18. Federal due date: 2025-01-08.
The impacted product is end-of-life (EoL) and/or end-of-service (EoS). Users should discontinue utilization of the product.
Impact
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.
