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 Endpoint Denial of Service (T1499); ranked in the top 47% 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.

SC-6 Resource Availability
addresses: CWE-410

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.

PR.IR-04 full match
prevents

Directly requires maintaining adequate resource capacity to ensure availability, which prevents exhaustion attacks from insufficient pools.

PR.AA-05 mostly match
prevents

Enforcing least-privilege authorization policies directly prevents external actors from acquiring or influencing locks.

PR.IR-01 mostly match
prevents

Logical access controls and segmentation stop unintended external influence over synchronization primitives.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly include code reviews, static analysis, and concurrency standards that prevent improper locking.

ID.RA-01 partial match
prevents

Vulnerability identification processes can discover externally controllable locks before deployment.

PR.PS-01 partial match
prevents

Hardened configuration baselines can disable or restrict external lock exposure by default.

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.

A.8.6 Capacity management full match
degrades

Capacity management directly addresses sizing resource pools to handle peak demand and prevent exhaustion.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect race conditions and locking errors before release.

A.8.14 Redundancy of information processing facilities partial match
mitigates

Redundancy of processing facilities mitigates resource exhaustion by providing failover capacity.

A.8.18 Use of privileged utility programs partial match
mitigates

Restricting privileged utilities can limit external lock manipulation but does not address the core weakness.

A.8.2 Privileged access rights partial match
mitigates

Privileged access rights limit who can create or manipulate locks, reducing external influence.

A.8.20 Networks security partial match
mitigates

Network security measures can block external access paths to locks but do not address the design flaw itself.
