CVE-2020-5722 is an unauthenticated SQL injection vulnerability in the HTTP interface of Grandstream UCM6200 series devices. A remote attacker can send a crafted HTTP request to inject SQL statements without authentication. On affected versions prior to 1.0.19.20, the flaw can be leveraged to achieve shell command execution as root, indicating that the SQL injection can be chained into operating-system command execution through backend application logic. On versions prior to 1.0.20.17, the vulnerability can also be used to inject HTML content into password recovery emails. The issue affects internet-exposed UCM6200 appliances through their web management interface and has been observed in botnet exploitation activity because it is remotely reachable and does not require credentials.
