CVE-2026-40552

Full vulnerability record from the local CVENow database.

Description

Multiple BinSoft products are vulnerable to Remote Command Execution. An authorized user with access to the application and direct access to the backend database can achieve system command execution by uploading an attachment and modifying its storage path in the database to reference an attacker-controlled remote network resource. Alternatively, it is possible to use a previously uploaded file and change its reference. When the application processes the attachment, and a user tries to open it, the referenced resource is executed by the system. Critically, this vulnerability can be exploited by any unauthenticated attacker by chaining it with CVE-2026-40550 and CVE-2026-40551, which allows obtaining database access, and logging onto any account. The described issue affects all published versions. The vendor stated that this issue is a direct result of the architecture model in which the software is distributed, and that it will be mitigated with a corrected installation manual.

      "value": "Múltiples productos BinSoft son vulnerables a la Ejecución Remota de Comandos. Un usuario autorizado con acceso a la aplicación y acceso directo a la base de datos de backend puede lograr la ejecución de comandos del sistema al cargar un archivo adjunto y modificar su ruta de almacenamiento en la base de datos para hacer referencia a un recurso de red remoto controlado por un atacante. Alternativamente, es posible usar un archivo cargado previamente y cambiar su referencia. Cuando la aplicación procesa el archivo adjunto, y un usuario intenta abrirlo, el recurso referenciado es ejecutado por el sistema.\nCríticamente, esta vulnerabilidad puede ser explotada por cualquier atacante no autenticado encadenándola con CVE-2026-40550 y CVE-2026-40551, lo que permite obtener acceso a la base de datos e iniciar sesión en cualquier cuenta.\n\nEl problema descrito afecta a todas las versiones publicadas. El proveedor declaró que este problema es un resultado directo del modelo de arquitectura en el que se distribuye el software, y que se mitigará con un manual de instalación corregido."
