Short explanation
A vulnerability in Apache Axis 1.x allows unauthenticated remote class instantiation and remote code execution when suitable classes are present. Apache Axis 1 has reached end-of-life and the project does not expect to release an official fix.
Authentication mechanisms fail to protect against this flaw because fault parsing occurs while resolving the target service before per-service handler chains execute, allowing attackers to achieve remote code execution.
What should be done?
- Migrate to a different SOAP engine such as Apache Axis 2/Java
- Use a build of Axis with the provided patch applied
Chain of evidence and sources
Apache Axis 1.x sürümleri, kimlik doğrulaması gerektirmeyen uzaktan sınıf örneklendirmesine ve uzaktan kod yürütülmesine karşı savunmasızdır.
Hata işleme aşaması servis işleyici zincirlerinden önce çalıştığı için servis yapılandırmalı kimlik doğrulama handler'ları bu zafiyeti engellemez.
Show the technical text from the sources
** 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.
