Remote Code Execution via Path Traversal in Advantech DeviceOn/iEdge Configuration Upload

IdentifiersCVE-2025-62630CWE-22· Improper Limitation of a Pathname…

CVE-2025-62630 is a high-severity vulnerability in Advantech DeviceOn/iEdge caused by insufficient sanitization of uploaded configuration files. The upload handling permits directory traversal, allowing a low-privileged remote attacker to supply a specially crafted configuration file containing path traversal sequences and write or place content outside the intended directory. According to the provided information, successful exploitation can lead to remote code execution with system-level permissions. The issue is therefore a path traversal flaw in the configuration file upload mechanism that can be reached remotely and does not require user interaction.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation can result in remote code execution with system-level privileges on the affected DeviceOn/iEdge system. This implies full compromise of the vulnerable host or appliance, including the ability to execute arbitrary commands or payloads, alter system state, access or modify sensitive data, and disrupt service availability. The provided context indicates high impact across confidentiality, integrity, and availability.

Mitigation

If you can’t patch tonight, do this now.

Until a patch is applied, restrict access to the configuration upload/import functionality to only trusted administrative users and management networks, disable the feature if operationally feasible, and place the interface behind network segmentation or VPN-only access. Validate and sanitize all uploaded file paths, restrict upload destinations to a non-executable dedicated directory, and run the relevant service with least privilege so uploaded content cannot be written or executed with system-level permissions. Monitor for suspicious configuration uploads and attempted traversal patterns, especially where public proof-of-concept code may be used.

Remediation

Patch, then assume compromise.

Apply the vendor's security update or fixed release for Advantech DeviceOn/iEdge as soon as it becomes available, and follow CISA advisory ICSA-25-310-01. In addition, correct the upload handling logic so configuration file uploads are strictly sanitized and canonicalized before use, reject path traversal sequences and absolute paths, enforce allowlisted filenames and destinations, and ensure uploaded files cannot be written outside a dedicated restricted directory. Review the configuration import feature for any code paths that process uploaded files with elevated privileges.
