CVE-2022-26080Network attack vector

Session hijacking via predictable 16-bit identifiers

Published Mar 16, 2023 · Updated Feb 26, 2025

Session ID weakness in ABB Pulsar Plus System Controller and Infinity DC Power Plant allows remote authenticated users to hijack sessions. The web server issues 16-bit session IDs that increment predictably and exposes them in page URLs, enabling an observed ID to reveal other valid session values. Exploitation requires network access, a successful login to obtain a session ID, and user interaction; a hijacked session can expose data or permit high-impact changes.
