CRITICAL
Type:
CWE-306 Missing Authentication for Critical Function

Description

FUXA is a web-based Process Visualization (SCADA/HMI/Dashboard) software. An information disclosure vulnerability in FUXA allows an unauthenticated, remote attacker to retrieve sensitive administrative database credentials. Exploitation allows an unauthenticated, remote attacker to obtain the full system configuration, including administrative credentials for the InfluxDB database. Possession of these credentials may allow an attacker to authenticate directly to the database service, enabling them to read, modify, or delete all historical process data, or perform a Denial of Service by corrupting the database. This affects FUXA through version 1.2.9. This issue has been patched in FUXA version 1.2.10.
