CVE-2025-28384 is a critical-severity Path Traversal (CWE-22) vulnerability in Openc3 Cosmos. Its CVSS base score is 9.1 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 45% 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-2025-28384 is a directory traversal vulnerability in the /script-api/scripts/ endpoint of OpenC3 COSMOS versions prior to 6.1.0. The flaw is tracked under CWE-22 and carries a CVSS 3.1 score of 9.1, reflecting network-accessible exploitation with no required credentials or user interaction and high impact on confidentiality and integrity.
An unauthenticated attacker can send crafted requests to the affected endpoint to traverse directories on the server, enabling unauthorized access to files and potential modification of system contents. The vulnerability affects any deployment exposing the script API without additional access controls.
The referenced GitHub pull request and v6.1.0 release tag indicate that the issue is resolved by upgrading to OpenC3 COSMOS 6.1.0, which contains the fix committed in fc7e11310a7cdf9f1939886e1b29009db4d4b718. The project site and an independent security assessment of the framework provide further context on the affected component.
EPSS remains flat at 0.0216 with no material increase after 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.

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

Security testing in development catches path traversal via static/dynamic analysis.
Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.
Application security requirements include rules for safe file handling and canonicalization.
Secure architecture principles require least-privilege file access and directory isolation.
Secure coding standards explicitly forbid unsafe path construction and mandate safe APIs.
Information access restriction limits which files an application may read or write.
