Name of the Vulnerable Software and Affected Versions PHOENIX CONTACT WP 6xxx series web panels versions prior to 4.0.10

Description The issue is related to the use of hardcoded credentials in PHOENIX CONTACT WP 6xxx series web panels. An authenticated, remote attacker with admin privileges can read hardcoded cryptographic keys, allowing them to decrypt an encrypted web application login password. This could enable the attacker to gain unauthorized access to protected information and compromise its integrity.

Recommendations For versions prior to 4.0.10, update to version 4.0.10 or later to resolve the issue. As a temporary workaround, consider restricting access to the web panels to minimize the risk of exploitation. Additionally, limit the use of admin privileges to only necessary users to reduce the potential impact of the vulnerability.
