CVE-2012-0838: Input Validation
First published: Fri Mar 02 2012(Updated: )
Apache Struts 2 before 2.2.3.1 evaluates a string as an OGNL expression during the handling of a conversion error, which allows remote attackers to modify run-time data values, and consequently execute arbitrary code, via invalid input to a field.
