CVE-2025-6218
RARLAB WinRAR Directory Traversal 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 handling of file paths within archive files. A crafted file path can cause the process to traverse to unintended directories. An attacker can leverage this vulnerability to execute code in the context of the current user. Was ZDI-CAN-27198.

Esta vulnerabilidad permite a atacantes remotos ejecutar código arbitrario en las instalaciones afectadas de RARLAB WinRAR. Para explotar esta vulnerabilidad, se requiere la interacción del usuario, ya que el objetivo debe visitar una página maliciosa o abrir un archivo malicioso. La falla específica se encuentra en la gestión de rutas de archivo dentro de los archivos comprimidos. Una ruta de archivo manipulada puede provocar que el proceso acceda a directorios no deseados. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto del usuario actual. Era ZDI-CAN-27198.\n"
