CVE-2025-2071Network attack vector

Unauthenticated command execution via hd and pi parameters

Published Mar 31, 2025 · Updated Mar 31, 2025

OS command injection in FAST LTA Silent Brick WebUI before 2.63.04 allows remote attackers to execute system commands via crafted input. The hd and pi WebUI parameters pass untrusted input directly to system-level commands without adequate validation or sanitization. No authentication or user interaction is required, and exploitation can expose data, alter system state, or compromise the appliance.
