CVE-2026-60063

AutomationDirect Productivity Suite Out-of-bounds Write

Published Jul 16, 2026 CVSS 4.0 · 7.3 High EPSS < 1% KEV · Not listed

Description

An out-of-bounds write vulnerability in the Productivity Suite allows a
local attacker to trigger kernel memory corruption via a crafted IOCTL
request, potentially resulting in privilege escalation or system
instability.

Analysis

Technical 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.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

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.
