22) Insufficient Resource Pool

EUVDB-ID: #VU21694

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-0056

CWE-ID: N/A

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause a denial of service (DoS) condition.

The vulnerability exists due to the device's resource pool is not large enough to handle peak demand. A remote attacker can cause the device's Open Shortest Path First (OSPF) states to transition to Down and perform a denial of service attack.

Note: This issue only affects devices with three (3) or more MPC10's installed in a single chassis with OSPF enabled and configured on the device.

Mitigation

Install updates from vendor's website.
