EnShare IoT Gigabit Cloud Service - RCE (CVE-2025-34035)

CVE-2025-34035 is a critical OS command injection vulnerability in EnGenius EnShare Cloud Service versions 1.4.11 and earlier, allowing unauthenticated remote attackers to execute arbitrary shell commands as root via the usbinteract.cgi script. This flaw enables full system compromise, making it possible for attackers to take complete control of affected devices. Evidence of active exploitation has already been observed, highlighting the urgent need for remediation.

CrowdSec has been tracking this vulnerability and its exploits since 15th of April 2026.

CrowdSec network observations suggest that most exploitation of CVE-2025-34035 involves focused reconnaissance to identify viable targets. Attackers typically tailor their campaigns based on system exposure and configuration. It is unlikely that a given attack is accidental. CrowdSec network telemetry also shows that exploitation of CVE-2025-34035 has significantly declined over the past week. Attack volumes are well below the long-term average, suggesting attackers are rapidly losing interest. The vulnerability appears to be falling out of active use across most threat landscapes.

Attackers exploit the /web/cgi-bin/usbinteract.cgi or /cgi-bin/usbinteract.cgi endpoints by injecting OS commands via the path parameter in POST requests, enabling unauthenticated remote code execution with root privileges.
