Description
Apache Struts 2.3.1.2 and earlier, 2.3.19-2.3.23, provides interfaces that do not properly restrict access to collections such as the session and request collections, which might allow remote attackers to modify run-time data values via a crafted parameter to an application that implements an affected interface, as demonstrated by the SessionAware, RequestAware, ApplicationAware, ServletRequestAware, ServletResponseAware, and ParameterAware interfaces. NOTE: the vendor disputes the significance of this report because of an "easy work-around in existing apps by configuring the interceptor."

Remediation
Red Hat statement
A previous statement by Red Hat related to this CVE, prior to August 2019, said that Apache Struts 2 is not included in any Red Hat products. This earlier statement was incorrect. While Struts 2 is not actively compiled, shipped, used, or enabled in any Red Hat provided final products, and does not cause any vulnerability in the product, struts2-core jars have been included in some products' source code packages. The inclusion was part of an import of the Google Guice repository, which includes struts2-core. Customers that build artefacts from our source code could be at risk. Red Hat will remove these artefacts from source code in future releases. The products that included the Struts 2 artefacts in their source jars: Fuse Service Works 6.0.0 Single Sign On 7.3.0+ If you have used the source package from one of these products to build artefacts on your system, you should do the following to remove potentially affected jars: 1. Run 'find . -name struts2*.jar' under the source location 2. Remove any files found This will not affect the product, as the jar is included with the source of google-guice, but no functionality requiring struts2 is implemented.
