WAGO: Smart Script affected by Log4Shell Vulnerability
Apache Log4j is used for logging events in WAGO Smart Script in Version 4.2 and higher. Events logged by Log4j can contain JNDI references. An attacker who can control log messages or log message parameters can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled. Additionally, Log4j does not protect from self-referential lookups, which can lead to Denial of Service. UPDATE A1/2: Affected versions: CVE-2021-44228 and CVE-2021-45046: WAGO Smart Script >= Version 4.2 and < Version 4.8.1.3 CVE-2021-45105: WAGO Smart Script >= Version 4.2 and < Version 4.8.1.4 CVE-2021-44832 WAGO Smart Script >= Version 4.2 and < Version 4.8.1.5 END UPDATE A1/2
