OGNL provides, among other features, extensive expression evaluation capabilities. This vulnerability allows a malicious user to bypass the ‘#’-usage protection built into the ParametersInterceptor, thus being able to manipulate server side context objects. This behavior was already addressed in S2-003, but it turned out that the resulting fix based on whitelisting acceptable parameter names closed the vulnerability only partially.
