CVE-2022-25017Public exploitNetwork attack vector

Authenticated command execution via unsanitized DDNS username

Published Apr 1, 2022 · Updated Aug 3, 2024

OS command injection in the Device/DDNS handler in Hitron CHITA 7.2.2.0.3b6-CD allows remote authenticated users to execute commands. The handler fails to sanitize semicolon-delimited shell syntax in ddnsUsername before processing the dynamic-DNS configuration. Administrative web access is required; a nonterminating injected command can persist across restarts and leave the web panel unusable until a factory reset.
