[jira] [Created] (IO-712) SecurityExceptions are hidden instead of breaking the regular flow

Boris Unckel created IO-712:
-------------------------------

             Summary: SecurityExceptions are hidden instead of breaking the regular flow
                 Key: IO-712
                 URL: https://issues.apache.org/jira/browse/IO-712
             Project: Commons IO
          Issue Type: Bug
          Components: Utilities
    Affects Versions: 2.8.0
            Reporter: Boris Unckel


Several points in the code hide SecurityException. These _must_ always _break_ the regular control flow, if you're not the SecurityManager. 

UseCase A: One wants to configure the SecurityManager and grant permissions. Part of the application is to delete a file. If the permission is missing, cleaning does not work. The missing exception does not allow to recognize that.
 UseCase B: One has activated the SecurityManager. An attacker abuses the relevant method. The missing SecurityException hides this attempt, ones IDS can't alarm.
 UseCase C: One utilizes the SecurityManager to test the system, to ensure every property (like file location) is set properly. The missing SecurityException does not support this UseCase.
