Description

OpenSymphony XWork vulnerable to improper input validation

XWork is an command-pattern framework that is used to power WebWork as well as other applications. 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 form input beginning with a "%{" sequence and ending with a "}" character.

Note: Version 2.0.4 marks the change from opensymphony:xwork to com.opensymphony:xwork.

Weakness class

CVE-2007-4556 is classified as CWE-20: Improper Input Validation. The application accepts input without checking that it has the expected form, so malformed values reach code that assumes they are well formed.
