Security Bulletin

This security bulletin contains information about 6 vulnerabilities.

1) Use of hard-coded credentials

EUVDB-ID: #VU105735

Risk: High

CVSSv4.0: 7.2 [CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2024-50692

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 MQTT credentials in application code. A remote unauthenticated attacker can access the affected system 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.
