CVE-2026-9593

iDTM FDI Unauthorized Debug Interface Enablement

Published Aug 3, 2026 CVSS 4.0 · 8.4 High EPSS < 1% KEV · Not listed
Description
A vulnerability in the iDTM FDI allows an attacker with elevated privileges and access to the host system to enable the debug interface by placing a crafted file in the application directory, potentially resulting in unauthorized access to connected devices and exposure, modification, or disruption of device data or operation.

Analysis

AI-generated

Technical impact

A local attacker who has elevated privileges on the host system can place a specially crafted file into the application directory of the iDTM FDI package library, causing the debug interface to be enabled. This allows the attacker to access or modify connected devices, potentially exposing sensitive data, altering device behavior, or disrupting device operations. The flaw directly grants unauthorized access to device functionality and data integrity.

Affected Systems

The vulnerability affects Endress+Hauser FDI Package Library. No specific version numbers are listed in the CNA data, so any deployment of the FDI package library with the described file placement capability is potentially impacted. The issue arises when the application directory is writable by privileged users.

Risk and Exploitability

The CVSS score of 8.4 indicates high severity. EPSS is not available, and the vulnerability is not in the CISA KEV catalog. The attack requires a user with elevated privileges to write to the application directory, implying a local attack vector. Once the crafted file is detected, the debug interface is activated, providing further control over connected devices. No public exploit is known, but the high severity and local privilege requirement suggest that the risk is significant for environments with limited user separation and where the FDI package library is actively used.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Revoke write permissions to the FDI application directory for non-admin users so that only trusted administrators can place files there.
  • Implement integrity checks or file monitoring on the application directory to detect and alert on unexpected files.
  • If the debug interface is not required operationally, disable or remove it from the deployment following vendor guidance.
