Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) OS Command Injection
EUVDB-ID: #VU71791
Risk: Medium
CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-42140
CWE-ID:
CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
Exploit availability: No
