Weakness Name
Use of Client-Side Authentication
Description
A client/server product performs authentication within client code but not in server code, allowing server-side authentication to be bypassed via a modified client that omits the authentication check.
Client-side authentication is extremely weak and may be breached easily. Any attacker may read the source code and reverse-engineer the authentication mechanism to access parts of the application which would otherwise be protected.
Common Consequences
Scope: Access Control
Impact: Bypass Protection Mechanism, Gain Privileges or Assume Identity
