In Digi RealPort through 4.10.490, authentication relies on a challenge-response mechanism that gives access to the server password, making the protection ineffective. An attacker may send an unauthenticated request to the server. The server will reply with a weakly-hashed version of the server's access password. The attacker may then crack this hash offline in order to successfully login to the server. En Digi RealPort hasta la versión 4.10.490, la autenticación se basa en un mecanismo de desafío-respuesta que da acceso a la contraseña del servidor, lo que hace que la protección sea ineficaz. • https://raw.githubusercontent.com/reidmefirst/vuln-disclosure/main/2021-02.txt • CWE-916: Use of Password Hash With Insufficient Computational Effort •
