CVE-ID: CVE-2021-27928

CWE-ID: CWE-77 - Command injection

Exploit availability: Yes

Description

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

2) OS Command Injection

EUVDB-ID: #VU49122

Risk: High

CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
