CVE-2026-44402
Voltronic Power SNMP Web Pro 1.1 Unauthenticated RCE via upload.cgi
Description
Voltronic Power SNMP Web Pro 1.1 contains an unauthenticated remote code execution vulnerability in the upload.cgi firmware update endpoint that allows remote attackers to execute arbitrary commands as root by uploading a crafted tar archive without valid credentials. Attackers can supply a malicious tar archive containing arbitrary executable files that are extracted to a privileged directory and executed as root, achieving full system compromise.
