Successful exploitation of these vulnerabilities could allow attackers to bypass authentication, gain unauthorized access to critical functions, and execute malicious server-side includes (SSI) within a web page.
The following versions of KUNBUS Revolution Pi are affected:
Revolution Pi OS Bookworm: Versions 01/2025 and earlier
Revolution Pi PiCtory: Versions 2.5.0 through 2.11.1
Revolution Pi PiCtory: Versions 2.11.1 and earlier
KUNBUS Revolution Pi OS Bookworm 01/2025 is vulnerable because authentication is not configured by default for the Node-RED server. This can give an unauthenticated remote attacker full access to the Node-RED server where they can run arbitrary commands on the underlying operating system.
CVE-2025-24522 has been assigned to this vulnerability. A CVSS v3.1 base score of 10.0 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).
A CVSS v4 score has also been calculated for CVE-2025-24522. A base score of 9.3 has been calculated; the CVSS vector string is (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N).
KUNBUS PiCtory versions 2.5.0 through 2.11.1 have an authentication bypass vulnerability where a remote attacker can bypass authentication to get access due to a path traversal.
CVE-2025-32011 has been assigned to this vulnerability. A CVSS v3.1 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
A CVSS v4 score has also been calculated for CVE-2025-32011. A base score of 9.3 has been calculated; the CVSS vector string is (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N).
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).
A CVSS v4 score has also been calculated for CVE-2025-35996. A base score of 8.5 has been calculated; the CVSS vector string is (AV:N/AC:L/AT:N/PR:L/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N).
KUNBUS PiCtory version 2.11.1 and earlier are vulnerable to a cross-site-scripting attack via the sso_token used for authentication. If an attacker provides the user with a PiCtory URL containing an HTML script as an sso_token, that script will reply to the user and be executed.
CVE-2025-36558 has been assigned to this vulnerability. A CVSS v3.1 base score of 6.1 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N).
A CVSS v4 score has also been calculated for CVE-2025-36558. A base score of 5.1 has been calculated; the CVSS vector string is (AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N).
Adam Bromiley of Pen Test Partners reported these vulnerabilities to CISA.
KUNBUS has identified the following specific mitigations that users can apply to reduce risk:
The preferred method for updating to version 2.12 is accomplished through KUNBUS's management UI Cockpit. However, users can also download the update package here.
By end of April 2025, KUNBUS plans to release a new Cockpit plugin that helps the user to make configurations which are available in a graphical interface. In the meantime, it is recommended that users activate authentication. Please refer to this guide for help with activating authentication.
CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities, such as:
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.
No known public exploitation specifically targeting these vulnerabilities has been reported to CISA at this time.
