Description Vincent Danen 2012-01-11 05:24:53 UTC

Common Vulnerabilities and Exposures assigned an identifier CVE-2011-5057 to
the following vulnerability:

Name: CVE-2011-5057
URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-5057
Assigned: 20120108
Reference: http://codesecure.blogspot.com/2011/12/struts-2-session-tampering-via.html
Reference: https://issues.apache.org/jira/browse/WW-2264
Reference: https://issues.apache.org/jira/browse/WW-3631
Reference: http://secunia.com/advisories/47109

Apache Struts 2.3.1.1 and earlier 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."

This issue only affects struts 2.

Comment 3 Chess Hazlett 2019-09-17 20:40:55 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.
