A flaw was discovered in jackson-databind in versions before 2.9.10, 2.8.11.5 and 2.6.7.3, where it would permit polymorphic deserialization of a malicious object using commons-configuration 1 and 2 JNDI classes. An attacker could use this flaw to execute arbitrary code.

It was found that a flaw in commons-collection library allowed remote code execution wherever deserialization occurs. While JBoss doesnt expose the JMXInvokerServlet by default, other interfaces where deserialization occur might be vulnerable.

Note: classes directly referenced by this flaw: InvokerTransformer, InstantiateFactory, and InstantiateTransformer

A flaw was found in the Undertow DEBUG log for io.undertow.request.security. If enabled, an attacker could abuse this flaw to obtain the user’s credentials from the log files.

A flaw was found when an OpenSSL security provider is used with Wildfly, the 'enabled-protocols' value in the Wildfly configuration isn't honored. An attacker could target the traffic sent from Wildfly and downgrade the connection to a weaker version of TLS, potentially breaking the encryption. This could lead to a leak of the data being passed over the network.
