CVE-2023-38505

Summary

CVE-2023-38505 is a vulnerability affecting the DietPi-Dashboard web application. In version 0.6.1, the dashboard permits only one TLS handshake at a time, assuming a new handshake request is in progress once a connection is made in HTTPS mode. An attacker can exploit this by not starting a handshake, preventing any further TLS handshakes and essentially locking the dashboard. This denial-of-service attack prevents legitimate traffic from reaching the dashboard and can last indefinitely. Version 0.6.2 includes a patch to address this issue. As a workaround, users are advised to avoid using HTTPS mode on open networks, and instead employ a reverse proxy to handle HTTPS connections.
