CISA Advisory
View CSAF Summary Successful exploitation of these vulnerabilities could allow an attacker to disclose information, brute-force hashes, or run arbitrary code in a browser session. The following versions of AVEVA Pipeline Integrity Monitor are affected: AVEVA Pipeline Integrity Monitor CVSS Vendor Equipment Vulnerabilities v3 8.4 AVEVA AVEVA Pipeline Integrity Monitor Use of Hard-coded Cryptographic Key, Use of a Broken or Risky Cryptographic Algorithm, Missing Authorization, Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') Background Critical Infrastructure Sectors: Critical Manufacturing Countries/Areas Deployed: Worldwide Company Headquarters Location: United Kingdom Vulnerabilities Expand All + CVE-2026-81821 The vulnerability, if exploited, could allow a miscreant with read access to PIMBoards project files to decrypt and view sensitive information. View CVE Details Affected Products AVEVA Pipeline Integrity Monitor Vendor: AVEVA Product Version: AVEVA Pipeline Integrity Monitor: Product Status: known_affected Remediations Vendor fix AVEVA recommends that organizations evaluate the impact of these vulnerabilities based on their operational environment, architecture, and product implementation. Customers using affected product versions or affected PIMBoards project files should take the following actions to mitigate the risk of exploit: Apply AVEVA Pipeline Integrity Monitor 2025 SP1 P2 Security Update and migrate old project files. For project files that cannot be migrated (e.g. backups or transient copies), evaluate the risk of potential password leakage from these files and implement stricter read access controls to protect these unsafe files. Require AVEVA Pipeline Integrity Monitor PIMBoards users to change their passwords. Vendor fix Important: PIMBoards Project Files migration from older versions to AVEVA Pipeline Integrity Monitor 2025 SP1 P2 is one-way due to the changes in password hashing algorithms and end-user managed encryption keys.

Adham Khairy Ramadan (0xadham) reported vulnerabilities CVE-2026-81823 and CVE-2026-81824 to AVEVA through HackerOne. Legal Notice and Terms of Use This product is provided subject to this Notification ( https://www.cisa.gov/notification ) and this Privacy & Use policy ( https://www.cisa.gov/privacy-policy ). 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.
