CVE-2026-9787
Full vulnerability record from the local CVENow database.
Description
Quest NetVault Backup NVBULogDaemon Command Injection Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Quest NetVault Backup. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the processing of NVBULogDaemon JSON-RPC messages. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of SYSTEM. Was ZDI-CAN-27625.

"value": "Vulnerabilidad de inyección de comandos y ejecución remota de código en Quest NetVault Backup NVBULogDaemon. Esta vulnerabilidad permite a atacantes remotos ejecutar código arbitrario en instalaciones afectadas de Quest NetVault Backup. Aunque se requiere autenticación para explotar esta vulnerabilidad, el mecanismo de autenticación existente puede ser eludido.\n\nLa falla específica existe en el procesamiento de los mensajes JSON-RPC de NVBULogDaemon. El problema se debe a la falta de validación adecuada de una cadena proporcionada por el usuario antes de usarla para ejecutar una llamada al sistema. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto de SYSTEM. Fue ZDI-CAN-27625."
