Affected by this issue is the function ajaxLogin of the file novel-admin/src/main/java/com/java2nb/system/controller/LoginController.java of the component CATCHA Handler. The manipulation leads to authentication bypass by capture-replay. The attack may be launched remotely. The complexity of an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way."},{"lang":"es","value":"Se ha detectado una vulnerabilidad clasificada como crítica en xxyopen/201206030 novel-plus hasta la versión 5.1.3. Este problema afecta a la función ajaxLogin del archivo novel-admin/src/main/java/com/java2nb/system/controller/LoginController.java del componente CATCHA Handler. La manipulación permite eludir la autenticación mediante captura y repetición. El ataque puede ejecutarse en remoto. Es un ataque de complejidad bastante alta. Parece difícil de explotar. Se ha hecho público el exploit y puede que sea utilizado.
