> Extend SecurityMemberAccess proxy detection to Hibernate proxies
> ----------------------------------------------------------------
>
> Key: WW-5407
> URL: https://issues.apache.org/jira/browse/WW-5407
> Project: Struts 2
> Issue Type: Improvement
> Components: Core
> Reporter: Kusal Kithul-Godage
> Priority: Minor
> Fix For: 6.5.0
>
> Time Spent: 1h
> Remaining Estimate: 0h
>
> The current option {{struts.disallowProxyMemberAccess}} does not have any
> logic to detect Hibernate proxies which may also present a security risk.
> Additionally, the current option only forbids access to members which
> originate from a proxy. However, it makes more sense to forbid access to
> proxy objects entirely. This is because proxying is often used for sensitive
> instances, application beans or Hibernate objects. None of which is safe to
> be accessed or manipulated via OGNL. Thus, let's introduce an additional
> option {{struts.disallowProxyObjectAccess}} which will offer stronger
> protection.
> Finally, the caching mechanism in the ProxyUtil class uses an unbounded map,
> this can potentially be attacked and lead to a memory leak or DoS. Let's
> replace it with a Caffeine cache as we have done previously for the OGNL
> expression cache.
