Raw vector
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2023-38505 is a high-severity Insufficient Resource Pool (CWE-410) vulnerability in Dietpi-Dashboard Project Dietpi-Dashboard. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique LSASS Memory (T1003.001); ranked in the top 44% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

Vulnerability Data
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.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Ensures a managed resource pool is maintained rather than allowing exhaustion by any single consumer.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Vulnerability identification processes can discover externally controllable locks before deployment.
Enforcing least-privilege authorization policies directly prevents external actors from acquiring or influencing locks.
Logical access controls and segmentation stop unintended external influence over synchronization primitives.
Hardened configuration baselines can disable or restrict external lock exposure by default.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Redundancy of processing facilities mitigates resource exhaustion by providing failover capacity.
Privileged access rights limit who can create or manipulate locks, reducing external influence.
Secure development lifecycle practices can prevent introducing externally controllable locks during design.
A.8.26 only requires that security requirements (including resilience against attacks such as injections) be identified and specified during development or acquisition; it does not itself enforce, implement, or prevent exploitation of an externally influenced lock.
A.8.27 mandates establishing and applying secure-by-design principles (defense-in-depth, least privilege, zero-trust, hardening, design review) but does not size or provision resource pools to handle peak demand, so the CWE-410 weakness can still be present and exploited.
Hardening callouts derived
DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.
- No fine-grained STIG row for CWE-410, a class-level weakness, and none of its children carries one either.
- No fine-grained STIG row for CWE-667, a class-level weakness, and none of its children carries one either.
