CVE-2024-22900Public exploitNetwork attack vector

Authenticated command execution via unsanitized network-card name

Published Feb 2, 2024 · Updated Jul 9, 2026

Command injection in Vinchin Backup & Recovery 7.2 allows remote authenticated users to execute arbitrary commands via the web API. In SystemHandler.class.php, setNetworkCardInfo copies the request's NAME value into a network-card path, concatenates that path into a cat command, and passes it to exec without validation. A valid web-console session cookie is required; successful injection runs commands with the web service's privileges and supports a reverse shell.
