Multiple vulnerabilities in Barco wePresent WiPG-1600W

1) Use of hard-coded credentials

EUVDB-ID: #VU48580

Risk: High

CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2020-28329

CWE-ID: CWE-798 - Use of Hard-coded Credentials

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain full access to vulnerable system.

The vulnerability exists due to presence of hard-coded credentials in application code, which include hardcoded credentials for the API and hardcoded password in clear text. A remote unauthenticated attacker can access the affected system via port 4001/tcp using the hard-coded credentials.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Install updates from vendor's website.
