Published: April 11, 2026
Official Description
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.
Technical Analysis
CVE-2025-34035 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2025-34035 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
