Technical details
The vulnerability stems from insufficient validation of backup file contents (CWE-434, CWE-94), allowing an authenticated administrator to inject malicious code that the gateway loads without proper sanitization. The attack requires network access and valid administrator credentials, with no user interaction needed. A successful exploit grants code execution as the underlying service account, enabling complete gateway compromise.
