CVE-2020-5725
The Grandstream UCM6200 series before 1.0.20.22 is vulnerable to an SQL injection via the HTTP server's websockify endpoint.
Does this matter?
Lower severity and a low EPSS score (1.75%). Track it; it rarely justifies an emergency change on its own.
Description
The Grandstream UCM6200 series before 1.0.20.22 is vulnerable to an SQL injection via the HTTP server's websockify endpoint. A remote unauthenticated attacker can invoke the login action with a crafted username and, through the use of timing attacks, can discover user passwords.
