CVE-2026-18293

OriginLab Origin Viewer OPJ File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of OriginLab Origin Viewer. 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 parsing of OPJ files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated data structure. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-29336.

Summary		(es) Vulnerabilidad de ejecución remota de código por escritura fuera de límites en el análisis de archivos OPJ de OriginLab Origin Viewer. Esta vulnerabilidad permite a atacantes remotos ejecutar código arbitrario en instalaciones afectadas de OriginLab Origin Viewer. Se requiere interacción del usuario para explotar esta vulnerabilidad, ya que el objetivo debe visitar una página maliciosa o abrir un archivo malicioso. La falla específica reside en el análisis de archivos OPJ. El problema se debe a la falta de validación adecuada de los datos proporcionados por el usuario, lo que puede resultar en una escritura más allá del final de una estructura de datos asignada. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto del proceso actual. Fue ZDI-CAN-29336.
