Known exploited

CISA added this to the Known Exploited Vulnerabilities Catalog on 18 Dec 2024. US federal agencies had to remediate by 8 Jan 2025, a deadline that has passed.

Required action. The impacted product is end-of-life (EoL) and/or end-of-service (EoS). Users should discontinue utilization of the product.

Description

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.
