Summary
RARLAB WinRAR Recovery Volume Improper Validation of Array Index Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of RARLAB WinRAR. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the processing of recovery volumes. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-21233.

Esta vulnerabilidad permite a atacantes remotos ejecutar código arbitrario en instalaciones afectadas de RARLAB WinRAR. Se requiere la interacción del usuario para aprovechar esta vulnerabilidad, ya que el objetivo debe visitar una página maliciosa o abrir un archivo malicioso. La falla específica existe en el procesamiento de volúmenes de recuperación. El problema se debe a la falta de una validación adecuada de los datos proporcionados por el usuario, lo que puede provocar un acceso a la memoria más allá del final de un búfer asignado. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto del proceso actual. Era ZDI-CAN-21233.",
