CVE-2024-23828Network attack vector

Authenticated command execution via CRLF configuration injection

Published Jan 29, 2024 · Updated Nov 12, 2024

Command injection in 0xJacky Nginx UI before 2.0.0.beta.12 allows remote authenticated users to execute commands on the host. The settings update path accepts CRLF characters in configuration values, allowing injected INI lines to replace test_config_cmd or start_cmd. A valid Nginx UI session and settings access are required; injected commands run with the service account's host privileges.
