KUNBUS PiCtory version 2.11.1 and earlier are vulnerable when an authenticated remote attacker crafts a special filename that can be stored by API endpoints. That filename is later transmitted to the client in order to show a list of configuration files. Due to a missing escape or sanitization, the filename could be executed as HTML script tag resulting in a cross-site-scripting attack.

CVE-2025-35996 has been assigned to this vulnerability. A CVSS v3.1 base score of 9.0 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H).

PLC Simulator for EcoStruxure Control Expert:

• A fix is available for (CVE-2018-7857) on PLC Simulator.

Schneider Electric recommends the following to help mitigate weaknesses in the management of Modbus protocol:

• Set up an application password in the project properties.
• Set up network segmentation and implement a firewall to block all unauthorized access to Port 502/TCP.
• Configure the access control list following the recommendations of user manuals.
• Set up secure communication according to the guidelines for the product.
• Consider use of an external firewall device.
• Please see SEVD-2019-134-11 for detailed mitigation information.

For more information see the associated Schneider Electric security advisory Modicon Controllers – SEVD-2019-134-11 PDF Version, Modicon Controllers – SEVD-2019-134-11 CSAF Version.

Schneider Electric strongly recommends the following industry cybersecurity best practices:

• Locate control and safety system networks and remote devices behind firewalls and isolate them from the business network.
• Install physical controls so no unauthorized personnel can access your industrial control and safety systems, components, peripheral equipment, and networks.
• Place all controllers in locked cabinets and never leave them in the “Program” mode.
• Never connect programming software to any network other than the network for the devices that it is intended.
• Scan all methods of mobile data exchange with the isolated network such as CDs, USB drives, etc. before use in the terminals or any node connected to these networks.
• Never allow laptops that have connected to any other network besides the intended network to connect to the safety or control networks without proper sanitation.
• Minimize network exposure for all control system devices and systems, and ensure that they are not accessible from the Internet.
• When remote access is required, use secure methods, such as virtual private networks (VPNs). Recognize that VPNs may have vulnerabilities and should be updated to the most current version available. Also, understand that VPNs are only as secure as the connected devices.

CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. 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. 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 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.

CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability, such as:

• 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.
