CVE-2024-44808Network attack vector

Unauthenticated code execution via unsanitized user parameter

Published Sep 4, 2024 · Updated Sep 4, 2024

Command injection in Vypor Attack API System 1.0 allows remote attackers to execute arbitrary code through the user GET parameter. The api.php frontend creates escaped local copies of the GET values but ignores them, concatenating the raw user, method, host, port, and time values into a quoted command passed to exec(). No authentication check precedes the call, so any remote requester that can reach the PHP endpoint can run commands with the web service account's privileges.
