The rhttpproxy must set a limit on established connections.
Overview
| Finding ID | Version | Rule ID | IA Controls | Severity |
|---|---|---|---|---|
| V-240717 | VCRP-67-000002 | SV-240717r679664_rule | Medium |
| Description |
|---|
| The rhttpproxy client connections must be limited to preserve system resources and continue servicing connections without interruption. Without a limit set, the system would be vulnerable to a trivial denial-of-service attack where connections are created en masse and vCenter resources are entirely consumed. The rhttproxy comes configured with a tested and supported value that must be maintained. |
