ICS Advisory ABB Ability Symphony Plus Engineering Release DateApril 30, 2026 Alert CodeICSA-26-120-06 Related topics: Industrial Control System Vulnerabilities, Industrial Control Systems View CSAF Summary ABB became aware of vulnerability in the products versions listed as affected in the advisory. The ABB S+ Engineering product versions are affected by vulnerabilities in PostgreSQL version 13.11 and earlier versions. If an attacker gains access to a site’s S+ Client Server network, they could exploit such vulnerabilities by executing arbitrary code and potentially compromising the entire system. The following versions of ABB Ability Symphony Plus Engineering are affected: Ability Symphony Plus 2.2, 2.3, 2.3_RU1, 2.3_RU2, 2.3_RU3, 2.4, 2.4_SP1, 2.4_SP2, 2.4_SP2_RU1 CVSS Vendor Equipment Vulnerabilities v3 8.8 ABB ABB Ability Symphony Plus Engineering Integer Overflow or Wraparound, Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection'), Time-of-check Time-of-use (TOCTOU) Race Condition, Privilege Dropping / Lowering Errors Background Critical Infrastructure Sectors: Chemical, Critical Manufacturing, Energy, Water and Wastewater Countries/Areas Deployed: Worldwide Company Headquarters Location: Switzerland Vulnerabilities Expand All + CVE-2023-5869 An attacker running as an authenticated PostgreSQL user can provide crafted data and trigger the integer overflow due to such missing overflow check. This can enable the execution of arbitrary code in the system.

The recommended immediate actions per product are listed below: - Systems using S+ Engineering 2.2 through 2.4 SP2 should upgrade to S+ Engineering 2.4 SP2 RU1 (re-leased in December 2024) or later. - End users who are unable to install one of these updates should immediately look to implement the Mitigation and Workarounds listed below as this will restrict or prevent an attacker’s ability to com-promise the system. ABB recommends that customers apply the update at the earliest convenience. MitigationAny exploit of these vulnerabilities would require that the attacker has access to the site’s S+ client/server network. Following ABB’s recommended security practices, including network architecture and perimeter firewall, are mitigating factors in preventing external access to the S+ client/server net-work. Refer to section “General security recommendations” for further advise on how to keep your system secure. WorkaroundNo workarounds are available. Assess the installation specific risk based on this advisory. Use the recommendations described under “Mitigating factors” or “Recommended immediate actions”.
