| Test ID: | 1.3.6.1.4.1.25623.1.0.80103 |
| Category: | Denial of Service |
| Title: | 3com switch2hub |
| Summary: | The remote host is subject to the switch to hub flood attack. |
| Description: | Summary: The remote host is subject to the switch to hub flood attack. Vulnerability Insight: The remote host on the local network seems to be connected through a switch which can be turned into a hub when flooded by different mac addresses. The theory is to send a lot of packets (> 1000000) to the port of the switch we are connected to, with random mac addresses. This turns the switch into learning mode, where traffic goes everywhere. Vulnerability Impact: An attacker may use this flaw in the remote switch to sniff data going to this host. Solution: Lock Mac addresses on each port of the remote switch or buy newer switch. CVSS Score: 7.8 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:N/A:C |
