CVE-2016-4461: Apache Struts

Apache Struts 2.x before 2.3.29 allows remote attackers to execute arbitrary code via a "%{}" sequence in a tag attribute, aka forced double OGNL evaluation. NOTE: this vulnerability exists because of an incomplete fix for CVE-2016-0785.

Affected products

• Apache Struts: from 2.0.0, before 2.3.29 (fixed in 2.3.29)
• Netapp Oncommand Balance: affected versions not specified
