What this means

Apache Axis 1.x through 1.4 allows unauthenticated remote class instantiation via a SOAP fault exceptionName. An attacker can exploit this by sending a crafted SOAP fault. The impact is related to deserialization of inbound SOAP faults.

Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.

Original source description

Read the full publisher 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.
