{"cve":"CVE-2023-38505","nvd":{"published":"2023-07-27T19:15:10.217","modified":"2026-06-17T06:10:36.300","status":"Modified","description":"DietPi-Dashboard is a web dashboard for the operating system DietPi. The dashboard only allows for one TLS handshake to be in process at a given moment. Once a TCP connection is established in HTTPS mode, it will assume that it should be waiting for a handshake, and will stay this way indefinitely until a handshake starts or some error occurs. In version 0.6.1, this can be exploited by simply not starting the handshake, preventing any other TLS handshakes from getting through. An attacker can lock the dashboard in a state where it is waiting for a TLS handshake from the attacker, who won't provide it. This prevents any legitimate traffic from getting to the dashboard, and can last indefinitely. Version 0.6.2 has a patch for this issue. As a workaround, do not use HTTPS mode on the open internet where anyone can connect. Instead, put a reverse proxy in front of the dashboard, and have it handle any HTTPS connections.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-667","CWE-410","CWE-412"],"references":["https://asciinema.org/a/8nRKbdf7AkPLmP3QxFZUSmPwp?t=7","https://github.com/ravenclaw900/DietPi-Dashboard/commit/79cd78615d28f577454415e4baafe4dcd9d09666","https://github.com/ravenclaw900/DietPi-Dashboard/pull/606","https://github.com/ravenclaw900/DietPi-Dashboard/security/advisories/GHSA-3jr4-9rxf-fr44","https://asciinema.org/a/8nRKbdf7AkPLmP3QxFZUSmPwp?t=7"],"products":["dietpi-dashboard_project:dietpi-dashboard"],"source":"nvd","synced_at":"2026-10-19T21:38:35.729974749+00:00"},"epss":{"cve":"CVE-2023-38505","score":0.00803,"percentile":0.5672,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
