QID Detection Logic (Authenticated):
The check matches Arista EOS version retrieved via Unix Auth using "show version" command.

Successful exploitation of this vulnerability can allow an attacker the capability to launch DoS attacks against servers or cause an out of memory (OOM) crash. Therefore the unusually slow network performance, unavailability of a particular website or a sudden loss of connectivity across devices on the same network can be used as indicators of the compromise for the vulnerabilities.

CVSS V3 rated as High - 7.5 severity.

CVSS V2 rated as Medium - 5 severity.
