Apache Struts 1 vulnerability that allows unintended remote operations against components on memory
Overview
The Apache Sturts 1 ActionForm contains a vulnerability which allows unintended remote operations against components on server memory, such as Servlets and ClassLoader.
Products Affected
- Apache Struts versions 1.0 through 1.3.10
Description
The Apache Sturts 1 ActionForm contains a vulnerability which allows unintended remote operations against components on server memory, such as Servlets and ClassLoader, when the following 2 conditions are met:
Condition 1:
- ActionForm (not including claesses that implement DynaBean interface, such as DynaActionForm and its subclasses)
- ValidatingActionForm
- ValidatorForm
- ValidatorActionForm
(This condition applies whether or not the web application uses multi-part forms)
Impact
Effects vary depending on the web application. For example, a denial-of-service (DoS) may occur.
Also, unintended operations on the ClassLoader by a remote attacker may lead to information being stolen or arbitrary code execution on the server where Apache Struts is running.
Solution
As of April 5, 2013, Apache Struts 1 is End-Of-Life (EOL).
For information on countermeasures and patches, refer to the information provided by developers that use Apache Struts 1.
