Technical Analysis
CVE-2026-44402 describes an unauthenticated remote code execution vulnerability in Voltronic Power SNMP Web Pro 1.1. The vulnerability exists in the upload.cgi endpoint used for firmware updates, which improperly handles uploaded tar archives. Attackers can supply a malicious tar archive that is extracted to a privileged directory and executed as root, enabling arbitrary command execution and complete system takeover without authentication.
Potential Impact
An attacker can achieve full system compromise with root privileges remotely and without authentication by exploiting this vulnerability. This allows arbitrary code execution on the affected device, potentially leading to complete control over the system and its functions.
