• → Monitor for unauthenticated HTTP GET/POST requests to /deployStart.php on ABB Cylon Aspect BMS/BAS controllers — no authentication is required to trigger command execution ↗
• → Alert on execution of rundeploy.sh from a web server process (e.g., lighttpd, Apache) context, as this indicates exploitation of CVE-2024-48840 ↗
• → Affected web servers include lighttpd/1.4.32, lighttpd/1.4.18, and Apache/2.2.15 (CentOS); scope detection rules to these server banners on ABB Aspect devices ↗

• · Vulnerability affects firmware versions up to and including 3.08.02 across NEXUS Series, MATRIX-2 Series, ASPECT-Enterprise, and ASPECT-Studio product lines ↗
• · The exploit was tested across multiple architectures (armv7l, x86_64) and multiple PHP versions (4.4.8 through 7.3.11), meaning detection must not be scoped to a single platform ↗
