CVE-2026-9781

Quest NetVault Backup NVBURASDevice SQL 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 NVBURASDevice JSON-RPC messages. The issue results from the lack of proper validation of a user-supplied string before using it to construct SQL queries. An attacker can leverage this vulnerability to execute code in the context of NETWORK SERVICE. Was ZDI-CAN-27648.

Summary		(es) Vulnerabilidad de inyección SQL y ejecución remota de código en NVBURASDevice de Quest NetVault Backup. 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. La falla específica existe en el procesamiento de mensajes JSON-RPC de NVBURASDevice. El problema resulta de la falta de validación adecuada de una cadena proporcionada por el usuario antes de usarla para construir consultas SQL. Un atacante puede aprovechar esta vulnerabilidad para ejecutar código en el contexto de NETWORK SERVICE. Fue ZDI-CAN-27648.
