CVE-2023-27886Public exploitNetwork attack vector

Unauthenticated command execution via pseudonym POST parameter

Published Mar 28, 2023 · Updated Jan 16, 2025

OS command injection in ProPump & Controls Osprey Pump Controller 1.01 allows remote attackers to execute shell commands via HTTP POST requests. The index.php script incorporates the pseudonym POST value into an operating-system command, so a semicolon introduces an additional command. No authentication or user interaction is required, and successful exploitation grants system access or interrupts controller operation.
