Summary

CVE-2025-62630 is a high-severity Path Traversal (CWE-22) vulnerability in Advantech Deviceon\/Iedge. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 45.7th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190) and 1 other technique. What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Directly addresses insufficient sanitization by requiring effective input validation on uploaded configuration files to reject or filter path traversal attempts.

SI-2 Flaw Remediation good match

prevent

Requires identification, reporting, and correction of the path traversal flaw through timely patching as recommended by the vendor.

CM-5 Access Restrictions for Change partial match

prevent

Enforces access restrictions on configuration change functions like file uploads, limiting exploitation to fewer low-privilege accounts.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

attack.mitre.org →

T1068 Exploitation for Privilege Escalation Privilege Escalation

Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.

attack.mitre.org →

Why these techniques?

The vulnerability allows remote exploitation of a network-accessible application via path traversal in uploaded configuration files, enabling arbitrary code execution with system-level privileges from low-privileged authentication (PR:L), directly mapping to T1190 (Exploit Public-Facing Application) and T1068 (Exploitation for Privilege Escalation).

NVD Description

Due to insufficient sanitization, an attacker can upload a specially crafted configuration file to traverse directories and achieve remote code execution with system-level permissions.

Deeper analysisAI

CVE-2025-62630 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. The vulnerability affects components detailed in CISA's Industrial Control Systems Advisory ICSA-25-310-01, with a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to network accessibility, low complexity, and low privilege requirements.

An authenticated attacker with low privileges (PR:L) can exploit this vulnerability remotely over the network by uploading a specially crafted configuration file. Successful exploitation allows the attacker to traverse directories and execute arbitrary code with system-level permissions, potentially leading to full compromise of the affected system, including high impacts on confidentiality, integrity, and availability.

CISA's ICSA-25-310-01 advisory provides details on mitigation, available at https://www.cisa.gov/news-events/ics-advisories/icsa-25-310-01, along with the corresponding CSAF JSON file at https://github.com/cisagov/CSAF/blob/develop/csaf_files/OT/white/2025/icsa-25-310-01.json.
