description: |
|
|
Apache Struts support in OpenSymphony XWork before 1.2.3, and 2.x before 2.0.4, as used in WebWork and Apache Struts, recursively evaluates all input as an Object-Graph Navigation Language (OGNL) expression when altSyntax is enabled, which allows remote attackers to cause a denial of service (infinite loop) or execute arbitrary code via for"m input beginning with a "%{" sequence and ending with a "}" character.

|
remediation: |
|
|
Update to the latest version of Apache Struts2
