Successful exploitation of these vulnerabilities could allow an attacker with local or physical access to cause memory corruption, unintended information disclosure, application instability, or a denial-of-service condition in the affected product.
The following versions of AutomationDirect Productivity Suite are affected:
Productivity Suite <=v4.6.2.2
Background
Critical Infrastructure Sectors: Critical Manufacturing
Countries/Areas Deployed: Worldwide
Company Headquarters Location: United States
Vulnerabilities CVE-2026-60073
An out-of-bounds read in the Productivity Suite allows a physical attacker to control the length of data sent to a USB device. This can lead to a system crash or disclosure of kernel memory.
Mitigation
AutomationDirect recommends that users update Productivity suite to v4.7.0.47 and above https://www.automationdirect.com/support/software-downloads.

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Continuously evaluate risks associated with running outdated firmware and adjust compensating measures accordingly.

Recommended Practices
CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities.
Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet.
Locate control system networks and remote devices behind firewalls and isolating them from business networks.
When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as the connected devices.
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets.
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.
CISA also recommends users take the following measures to protect themselves from social engineering attacks:
Do not click web links or open attachments in unsolicited email messages.
Refer to Recognizing and Avoiding Email Scams for more information on avoiding email scams.
Refer to Avoiding Social Engineering and Phishing Attacks for more information on social engineering attacks.
No known public exploitation specifically targeting these vulnerabilities has been reported to CISA at this time. These vulnerabilities are not exploitable remotely.
