AI Analysis

Impact

An out-of-bounds write flaw in the AutomationDirect Productivity Suite allows a local attacker to send a crafted IOCTL request that corrupts kernel memory. The memory corruption can enable an attacker to elevate privileges on the affected system, potentially compromising the integrity of the device and its control functions. The weakness is categorized as a buffer overflow (CWE-787).

Affected Systems

The affected product is AutomationDirect:Productivity Suite, used in industrial control environments. Versions prior to v4.7.0.47 are vulnerable; the vendor recommends upgrading to v4.7.0.47 or later.

Risk and Exploitability

The CVSS score of 7.3 indicates high severity, but the EPSS score of less than 1% shows a very low likelihood of exploitation in the wild. The flaw is not listed in the CISA KEV catalog. Exploitation requires local access to a machine running the affected software, such as a PLC engineering workstation, and the ability to issue a malicious IOCTL command. The vulnerability enables privilege escalation by an attacker who has local access.

Remediation

Vendor Solution

AutomationDirect recommends that users update Productivity suite to v4.7.0.47 and above  https://www.automationdirect.com/support/software-downloads

Vendor Workaround

If the update cannot be applied right away, the following compensating controls are recommended until the upgrade can be performed. * Disconnect the engineering workstation from external networks (e.g., the internet or corporate LAN) to reduce exposure. * Use only trusted, dedicated internal networks or air-gapped systems for device communication. * Restrict both physical and logical access to authorized personnel only. * Configure whitelisting so that only trusted, pre-approved applications are allowed to run. Block any unauthorized software. * Use antivirus or EDR tools and configure host-based firewalls to block unauthorized access attempts. * Enable and regularly review system logs to detect suspicious or unauthorized activity. * Maintain secure, tested backups of the PLC and its configurations to minimize downtime in case of an incident. * Continuously evaluate risks associated with running outdated firmware and adjust compensating measures accordingly.

OpenCVE Recommended Actions

  • Apply the vendor‑recommended update to Productivity Suite version 4.7.0.47 or newer
  • Disconnect engineering workstations from external networks to reduce exposure
  • Configure device communication to trusted, internal or air‑gapped systems only
  • Restrict both physical and logical access to authorized personnel only
  • Whitelist only trusted, pre‑approved applications on the workstation
  • Enable antivirus or EDR tools and configure host‑based firewalls to block unauthorized access attempts
  • Enable and regularly review system logs for suspicious activity
  • Maintain secure, tested backups of PLC configurations to minimize downtime
