Title
Apache Axis2/Java: deserialization of untrusted Data
Summary
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.
