Descriptions

An issue was discovered in Veritas NetBackup and OpsCenter through 8.3.0.1. NetBackup processes using Strawberry Perl attempt to load and execute libraries from paths that do not exist by default on the Windows operating system. By default, on Windows systems, users can create directories under C:\. If a low privileged user on the Windows system creates an affected path with a library that NetBackup attempts to load, they can execute arbitrary code as SYSTEM or Administrator. This gives the attacker administrator access on the system, allowing the attacker (by default) to access all data, access all installed applications, etc. This affects NetBackup master servers, media servers, clients, and OpsCenter servers on the Windows platform. The system is vulnerable during an install or upgrade on all systems and post-install on Master, Media, and OpsCenter servers during normal operations.

Se detectó un problema en Veritas NetBackup y OpsCenter versiones hasta 8.3.0.1. Los procesos de NetBackup que usan Strawberry Perl intentan cargar y ejecutar bibliotecas desde rutas que no existen por defecto en el sistema operativo de Windows. Por defecto, en los sistemas Windows, los usuarios pueden crear directorios en C:\. Si un usuario poco privilegiado en el sistema Windows crea una ruta afectada con una biblioteca que NetBackup intenta cargar, puede ejecutar código arbitrario como SYSTEM o Administrator. Esto le otorga al atacante acceso de administrador al sistema, permitiendo al atacante (por defecto) acceder a todos los datos, acceder a todas las aplicaciones instaladas, etc. Esto afecta a los servidores maestros, servidores multimedia, clientes y servidores OpsCenter de NetBackup en la plataforma Windows. El sistema es vulnerable durante una instalación o actualización en todos los sistemas y después de la instalación en Servidores Master, Multimedia, y OpsCenter durante las operaciones normales
