Vulnerability from fkie_nvd - Published: 2022-01-13 22:15 - Updated: 2024-11-21 06:11
Severity ?
8.8 (High) - CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Commvault CommCell 11.22.22. Although authentication is required to exploit this vulnerability, the existing authentication mechanism can be bypassed. The specific flaw exists within the DataProvider class. The issue results from the lack of proper validation of a user-supplied string before executing it as JavaScript code. An attacker can leverage this vulnerability to escape the JavaScript sandbox and execute Java code in the context of NETWORK SERVICE. Was ZDI-CAN-13755.

      "value": "Esta vulnerabilidad permite a atacantes remotos ejecutar c\u00f3digo arbitrario en las instalaciones afectadas de Commvault CommCell versi\u00f3n 11.22.22. Aunque es requerida una autenticaci\u00f3n para explotar esta vulnerabilidad, el mecanismo de autenticaci\u00f3n existente puede ser omitido. El fallo espec\u00edfico se presenta en la clase DataProvider. El problema es debido a una falta de comprobaci\u00f3n apropiada de una cadena suministrada por el usuario antes de ejecutarla como c\u00f3digo JavaScript. Un atacante puede aprovechar esta vulnerabilidad para escapar del sandbox de JavaScript y ejecutar c\u00f3digo Java en el contexto de NETWORK SERVICE. Fue ZDI-CAN-13755"
