What is CVE-2026-44402?

The Voltronic Power SNMP Web Pro 1.1 is susceptible to an unauthenticated remote code execution vulnerability through the upload.cgi firmware update interface. This flaw enables remote attackers to execute commands with root privileges simply by uploading a specially crafted tar archive, bypassing authentication measures. The malicious archive can contain executables that, when extracted to a privileged directory, compromise the entire system. This vulnerability underscores the critical need for proper input validation and security measures in firmware update endpoints.

Affected Version(s)

SNMP Web Pro 1.1
