Why this deserves its current priority

A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

Affected scope and exposure questions

The current feed maps Apache Software Foundation/Apache Axis 1.x (EOL) (generic), Apache Software Foundation/axis:axis (generic), Apache Software Foundation/org.apache.axis:axis (generic). Check affected ranges and fixed versions before updating.

Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for Apache Software Foundation/Apache Axis 1.x (EOL), Apache Software Foundation/axis:axis, Apache Software Foundation/org.apache.axis:axis.
  2. 2Review the reported fix. Update Apache Software Foundation/Apache Axis 1.x (EOL) to 41f3b4e8d04e310ca81f86b92630ab2c11d608bd if you use the affected versions. Test the change in a non-production environment first.

Upstream source description

** UNSUPPORTED WHEN ASSIGNED ** Deserialization of an inbound SOAP fault in Apache Axis 1.x allows unauthenticated remote class instantiation. When a SOAP <Fault> carries a <detail><exceptionName> element, Axis loads the named class and, if a String <data> element is also present, instantiates it through its String constructor before checking that it is an AxisFault. Loading alone runs the class's static initializer. With a suitable class on the application's classpath this leads to remote code execution. The fault is parsed while the engine resolves the target service, before any per-service handler chain runs, so authentication handlers configured on a service do not protect against it. This affects all Apache Axis 1.x versions through 1.4. As Axis 1 has been EOL we recommend you migrate to a different SOAP engine, such as Apache Axis 2/Java. Alternatively you could use a build of Axis with the patch from https://github.com/apache/axis-axis1-java/commit/41f3b4e8d04e310ca81f86b92630ab2c11d608bd applied. The Apache Axis project does not expect to create an Axis 1.x release fixing this problem.
