Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

Updated 27.05.2020
Added vulnerabilities #2-4

1) Improper access control

EUVDB-ID: #VU27076

Risk: High

CVSSv3.1: 7.9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2020-10641

CWE-ID: CWE-284 - Improper Access Control

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.

The vulnerability exists due to improper access restrictions. A remote attacker can write endless log statements into the database without space limits or authentication and cause a denial of service (DoS) condition on the target system.

Mitigation

Install updates from vendor's website.
