CVE-2025-34035: Engeniustech EPG5000 Firmware

Critical severity, CVSS 9.8. EPSS: 22.8% chance of exploitation in the next 30 days.

An OS command injection vulnerability exists in EnGenius EnShare Cloud Service version 1.4.11 and earlier. The usbinteract.cgi script fails to properly sanitize user input passed to the path parameter, allowing unauthenticated remote attackers to inject arbitrary shell commands. The injected commands are executed with root privileges, leading to full system compromise. Exploitation evidence was observed by the Shadowserver Foundation on 2024-12-05 UTC.
