CVE-2025-14850 is a high-severity Path Traversal (CWE-22) vulnerability in Advantech Webaccess\/Scada. Its CVSS base score is 7.2 (High).
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.
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-2025-14850 is a directory traversal vulnerability (CWE-22) in Advantech WebAccess/SCADA. Published on 2025-12-18T21:15:52.900, it carries a CVSS v3.1 base score of 8.1 (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H). The issue enables an attacker to delete arbitrary files on the affected system.
The vulnerability can be exploited remotely over the network by an attacker with low privileges, requiring low attack complexity and no user interaction. Successful exploitation allows deletion of arbitrary files, leading to high integrity and availability impacts but no confidentiality loss.
For mitigation guidance, refer to CISA ICS Advisory ICSA-25-352-06 at https://www.cisa.gov/news-events/ics-advisories/icsa-25-352-06, the corresponding CSAF JSON file at https://github.com/cisagov/CSAF/blob/develop/csaf_files/OT/white/2025/icsa-25-352-06.json, and Advantech's support details at https://www.advantech.com/en-us/support/details/installation?id=1-MS9MJV.

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.
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.
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.
