Root Cause Analysis

The vulnerability stems from insufficient validation of OGNL expressions during parameter handling. The patch introduced a new 'enableOGNLEvalExpression' flag and modified OgnlUtil.compile() to block eval expressions by default. The pre-patch versions allowed arbitrary OGNL evaluation via parameter names in redirects because:

compile() parsed user-controlled input without evaluating expression type
setValue() used compile() results directly
No mechanism existed to block eval chains like those used in S2-012 PoC. The functions handling OGNL parsing/execution (compile() and setValue()) were the entry points for code injection.
