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 insufficient authorization procedures in the web panels, allowing an unauthenticated remote attacker to access upload functions of the HTTP API. This could lead to certificate errors for SSL connections and potentially result in a partial denial-of-service, impacting the integrity and availability of protected information.

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 upload functions of the HTTP API until a patch is available.
