Description Pedro Sampaio 2017-08-11 13:36:21 UTC
A flaw was found in Apache Struts 2.3.7 through 2.3.32 and 2.5 through 2.5.10.1. When using a Spring AOP functionality to secure Struts actions it is possible to perform a DoS attack even if user was not properly authenticated but an application mixed secured and not secured actions in one class.

Comment 2 Chess Hazlett 2019-09-17 20:01:13 UTC
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.
