CWE - 649 : Reliance on Obfuscation or Encryption of Security-Relevant Inputs without Integrity Checking

CWE Definition http://cwe.mitre.org/data/definitions/649.html
Number of vulnerabilities: 0
Description The software uses obfuscation or encryption of inputs that should not be mutable by an external actor, but the software does not use integrity checks to detect if those inputs have been modified.When an application relies on obfuscation or incorrectly applied / weak encryption to protect client controllable tokens or parameters, that may have an effect on the user state, system state or some decision made on the server. Without protecting the tokens/parameters for integrity, the application is vulnerable to an attack where an adversary blindly traverses the space of possible values of the said token/parameter in order to attempt to gain an advantage. The goal of the attacker is to find another admissible value that will somehow elevate his or her privileges in the system, disclose information or change the behavior of the system in some way beneficial to the attacker. If the application fails to protect these critical tokens/parameters for integrity, it will not be able to determine that these values have been tampered with. Measures that are used to protect data for confidentiality should not be relied upon to provide the integrity service.
