Summary

OGNL is an object graph navigation library for Java. Prior to 3.4.13, the optional stricter-invocation mode does not block java.lang.reflect.Method, Constructor or Field, allowing an attacker-controlled expression to bypass the check and execute operations on blocked classes via JDK reflection.

Risk Assessment

Applications evaluating untrusted OGNL expressions and relying on stricter invocation as a sandbox may be forced to perform unauthorized operations. Applications using restrictive MemberAccess (e.g. Apache Struts with SecurityMemberAccess) are not affected.

Recommendation

Upgrade OGNL to version 3.4.13 or later. Ensure the application does not evaluate untrusted OGNL expressions and uses a restrictive MemberAccess.

Original NVD description (English source)

OGNL is an Object Graph Navigation Library for Java. Prior to 3.4.13, the optional stricter-invocation mode in OgnlRuntime.invokeMethod checks the declaring class of the method that OGNL invokes but does not block java.lang.reflect.Method, java.lang.reflect.Constructor, or java.lang.reflect.Field. An attacker-controlled expression can invoke one of these reflection objects as a proxy for a method on a blocked class, causing the real operation to execute inside JDK reflection without passing through the stricter-invocation check again. Exploitation requires an application to evaluate untrusted OGNL expressions, use the default or an equivalently permissive MemberAccess that permits reflection, and rely on stricter invocation as a sandbox. Applications using a restrictive MemberAccess, including Apache Struts with SecurityMemberAccess, are not affected by this bypass. This issue is fixed in 3.4.13.
