CVE-2023-3749

Service disruption via unverified configuration-file edits

Published Aug 3, 2023 · Updated Oct 9, 2024

Improper configuration-file validation in Johnson Controls VideoEdge before 6.1.1 allows local users to disrupt recorder operation. VideoEdge accepts edits by a low-privileged local user to an unspecified configuration file and processes the altered data without adequately validating its authenticity or excluding extraneous input. Johnson Controls has not identified the file or parsing path; exploitation requires local access and can alter configuration or interrupt operation.
