Summary

CVE-2025-59171 is a high-severity Path Traversal (CWE-22) vulnerability in Advantech Deviceon\/Iedge. Its CVSS base score is 8.7 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 50% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

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.

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

CVE-2025-59171 is a path traversal vulnerability (CWE-22) stemming from insufficient sanitization of uploaded configuration files, enabling directory traversal and subsequent remote code execution with system-level permissions. Published on 2025-11-06, it carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), indicating high confidentiality impact over the network with low attack complexity and no privileges required. The vulnerability affects industrial control systems (ICS) components as detailed in CISA advisory ICSA-25-310-01.

An unauthenticated remote attacker can exploit this vulnerability by uploading a specially crafted configuration file, traversing directories to access unauthorized paths, and achieving remote code execution at the system level. Successful exploitation grants high-level access, potentially allowing data exfiltration given the elevated confidentiality impact, though integrity and availability remain unaffected per the CVSS vector.

Mitigation details are outlined in the CISA ICS advisory at https://www.cisa.gov/news-events/ics-advisories/icsa-25-310-01 and the associated CSAF document at https://github.com/cisagov/CSAF/blob/develop/csaf_files/OT/white/2025/icsa-25-310-01.json, with Advantech recommending users contact support via https://www.advantech.com/emt/contact for patches and remediation guidance.

Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

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

SI-10 Information Input Validation good match

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

AC-6 Least Privilege partial match

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.

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.

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

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

A.8.25 Secure development life cycle partial match
prevents

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

A.8.26 Application security requirements partial match
prevents

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

A.8.27 Secure system architecture and engineering principles partial match
prevents

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

A.8.28 Secure coding partial match
prevents

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

A.8.3 Information access restriction partial match
mitigates

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