CWE - 768 : Incorrect Short Circuit Evaluation

CWE Definition http://cwe.mitre.org/data/definitions/768.html
Number of vulnerabilities: 0
Description The software contains conditionals with multiple logical expressions where one or more of the non-leading logical expressions produces side effects that may not be executed due to short circuiting logic. This may lead to an unexpected state in the program after the execution of the conditional.Usage of short circuit evaluation, though well-defined in the C standard, may alter control flow in a way that introduces logic errors that are difficult to detect, leading to error-prone conditions later in the software's life cycle. If an attacker can discover such an inconsistency, it may be exploitable to gain arbitrary control over a system. If the first condition of an "or" statement is assumed to be true under normal circumstances, or if the first condition of an "and" statement is assumed to be false, then any subsequent conditional may contain its own logic errors that are not detected during code review or testing. Finally, the usage of short circuit evaluation may decrease the maintainability of the code.
