Description

This security bulletin contains information about 1 security vulnerability.


1) Resource management error (CVE-ID: CVE-2020-3168)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper resource allocation during failed CLI login attempts when login parameters that are part of the Secure Login Enhancements capability are configured on an affected device. A remote attacker can perform a high amount of login attempts against the affected device and cause it to become inaccessible to other users, resulting in a denial of service condition requiring a manual power cycle of the VSM to recover.
