Operator-to-administrator escalation via unsanitized CGI command
Published Feb 7, 2020 · Updated Aug 4, 2024
OS command injection in EdgeMAX EdgeSwitch 1.7.0 allows local users to gain administrator privileges via CGI requests. The CGI script fails to sanitize user input before invoking local commands, enabling an operator-level account to execute commands with elevated rights. Exploitation requires an operator account and access to the switch management interface; successful use changes Privilege-1 access to administrator (Privilege-15).
