FKIE_CVE-2026-66713

Vulnerability from fkie_nvd - Published: 2026-07-28 15:17 - Updated: 2026-07-29 05:17
Severity
9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
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.
