Apache Tomcat: Deserialization of Untrusted Data (CWE-502) in the Tribes-based clustering component in Apache Software Foundation…
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.
What this means
In plain English
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. The official description indicates that exploitation does not require prior authentication. Successful exploitation can let an attacker run code in the security context of the affected service or device.
Vulnerable items
- Apache Tomcat — Apache Tomcat is a Java application server and servlet container used to host web applications.
- Apache Axis2
Recommended action
Primary action: update to a vendor-listed fixed release: 2.0.1. Vendor mitigation: Users are recommended to upgrade to version 2.0.1, which fixes this issue by removing the clustering feature entirely.
