Recommendation: Monitor — no exploitation signal at the moment.

In isServerCertChainValid of InsecureEapNetworkHandler.java, there is a possible way to trust an imposter server due to a logic error in the code. This could lead to remote escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
