1) OS command injection

EUVDB-ID: #VU12813

Risk: High

CVSSv3.1: 8.6 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-10730

CWE-ID: CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

Exploit availability: No

Description

The vulnerability allows a remote authenticated attacker to execute arbitrary code on the target system.

The weakness exists due to command injection. A remote attacker with permission to transfer configuration files to or from the switch or permission to upgrade firmware can execute arbitrary OS shell commands.
