Summary

CVE-2024-31818 is a critical-severity Path Traversal (CWE-22) vulnerability in Derbynet Derbynet. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 22% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2024-31818 is a directory traversal vulnerability, tracked under CWE-22, that affects DerbyNet version 9.0. The flaw resides in the kiosk.php component and is triggered through the page parameter, enabling path manipulation that can lead to arbitrary code execution. It carries a CVSS 3.1 score of 9.8, reflecting network-accessible exploitation with no required authentication or user interaction and full impact on confidentiality, integrity, and availability.

Unauthenticated remote attackers can supply crafted input to the page parameter over the network to traverse directories and execute arbitrary code on the underlying system, resulting in complete compromise of the affected DerbyNet instance.

Public references consist of technical write-ups on chocapikk.com that analyze the DerbyNet issues along with direct links to the vulnerable kiosk.php source on GitHub; these sources do not detail official patches or mitigation steps. The associated EPSS score stands at 0.1209 with no recorded increase from its peak, indicating steady but not accelerating exploitation interest since disclosure.

Mitigating Controls (NIST 800-53 r5) AI

Enforces the intended directory access authorizations that path traversal would otherwise bypass.

Input validation directly neutralizes special path elements before pathname construction occurs.

Least privilege reduces the impact of any unauthorized file access obtained via traversal.

PR.PS-02 partial match
prevents

Patching/maintenance can remediate known path-traversal flaws in deployed software (partial prevention of exploitability) but does nothing to stop the coding defect from being introduced in the first place.

PR.AA-05 none match
prevents

PR.AA-05 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.

finds

Security testing in development catches path traversal via static/dynamic analysis.

prevents

Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.

prevents

Application security requirements include rules for safe file handling and canonicalization.

prevents

Secure architecture principles require least-privilege file access and directory isolation.

prevents

Secure coding standards explicitly forbid unsafe path construction and mandate safe APIs.

mitigates

Information access restriction limits which files an application may read or write.
