Description

AI Translation Available

Deserialization of Untrusted Data (CWE-502) in the Tribes-based clustering component

 in Apache Software Foundation Apache Axis2/Java through 2.0.0 on Apache Tomcat

 (only when Tribes clustering is enabled, which is off by default) allows an

 unauthenticated remote attacker with network access to the clustering port to

 execute arbitrary code via a crafted serialized Java object delivered to the cluster

 channel and deserialized in

 org.apache.axis2.clustering.tribes.Axis2ChannelListener#messageReceived. Users are

 recommended to upgrade to version 2.0.1, which fixes this issue by removing the

 clustering feature entirely.
