An update is now available that addresses and remediates the vulnerability. An attacker who successfully exploited this vulnerability could read sensitive information in the logging data of the PVI client application. Logging is deactivated by default in all PVI client versions.\n\nThe following versions of ABB B&R PVI are affected:\n\n\n\nPVI <6.5.0, 6.5.0 (CVE-2026-0936)\n\n<div class=\"csaf-table\">\n\n\n\n\nCVSS\nVendor\nEquipment\nVulnerabilities\n\n\n\n\nv3 5\nABB\nABB B&R PVI\nInsertion of Sensitive Information into Log File\n\n\n\n</div>\n\nBackground\n\n\n\nCritical Infrastructure Sectors: Energy\n\nCountries/Areas Deployed: Worldwide\n\nCompany Headquarters Location: Switzerland\n\n\n\n\nVulnerabilities\n<div class=\"csaf-accordion\">\n\nExpand All +\n<div class=\"csaf-accordion-item\">\n\nCVE-2026-0936\n<div class=\"csaf-accordion-content\">\n\nAn Insertion of Sensitive Information into Log File vulnerability in B&R PVI client versions prior to 6.5 may be abused by an authenticated local attacker to gather credential information which is processed by the PVI client application. The logging function of the PVI client application is disabled by default and must be explicitly enabled by the user.\n\nView CVE Details\n\n\n\nAffected Products\n\nABB B&R PVI\n<div class=\"ics-vendor-version-status\">\n<div class=\"ics-vendor\">Vendor:ABB</div>\n<div class=\"ics-version\">Product Version:ABB PVI <6.5.0</div>\n<div class=\"ics-status\">Product Status:fixed, known_affected</div>\n</div>\n<div class=\"ics-remediations\">\n\nRemediations\n\nVendor fixThe problem is corrected in the following product versions: - PVI 6.5.0 Please note that PVI is included in the Automation Studio installation package and shares the same version number as the corresponding Automation Studio release. B&R recommends that customers apply the update at earliest convenience. The process to install updates is described in the user manual. The step to identify the installed product version is described in the user manual.\n\nMitigationThis vulnerability is limited to the PVI client side application logging and does not impact any security related logging of the PVI server component. Logging is not enabled by default for PVI client applications. Activate logging on the client system only when it is required for troubleshooting, debugging or analysis. Ensure that all client side logging information is securely deleted after it is no longer needed. When enabling logging in PVI client applications, the storage path for the log files must be specified. Make sure that only the respective user has access to the directories where the logging information is stored. Refer to section \u201cGeneral security recommendations\u201d for further advise on how to keep your system secure.\n</div>\n\nRelevant CWE: CWE-532 Insertion of Sensitive Information into Log File\n\n\n\nMetrics\n<div class=\"csaf-table csaf-metrics-table\">\n\n\n\n\nCVSS Version\nBase Score\nBase Severity\nVector String\n\n\n\n\n3.1\n5\nMEDIUM\nCVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C\n\n\n\n</div>\n</div>\n</div>\n</div>\n\n\n\nAcknowledgments\n\n\n\nABB PSIRT reported this vulnerability to CISA.\n\n\n\n\nNotice\n\nThe information in this document is subject to change without notice, and should not be construed as a commitment by B&R.

Also recognize VPN is only as secure as its connected devices.\n\nCISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.\n\nCISA 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.\n\nCISA 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.\n\nOrganizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.\n\n\n\nAdvisory Conversion Disclaimer\n\nThis ICSA is a verbatim republication of ABB PSIRT SA26P001 from a direct conversion of the vendor's Common Security Advisory Framework (CSAF) advisory.
