Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) SQL injection
EUVDB-ID: #VU68965
Risk: Medium
CVSSv3.1: 4.1 [CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-20867
CWE-ID:
CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Exploit availability: No
DescriptionThe vulnerability allows a remote user to execute arbitrary SQL queries in database.
The vulnerability exists due to insufficient sanitization of user-supplied data in the next-generation UI management interface. A remote privileged user can send a specially crafted request to the affected application and execute arbitrary SQL commands within the application database.
Successful exploitation of this vulnerability may allow a remote attacker to read, delete, modify data in database and gain complete control over the affected application.
MitigationInstall updates from vendor's website.
