CVE-2026-54363

CentreStack before 17.5 contains a hardcoded cryptographic key vulnerability that allows unauthenticated attackers to forge arbitrary encrypted tokens by exploiting a static SysNumber value used as entropy for AccessTicket.Encrypt() and AccessTicket.Decrypt() across all installations. Attackers can use the hardcoded key to craft valid x-glad-auth headers and call privileged API endpoints such as acquiretenantbackuptoken to obtain a domain administrator IdentityTicket, enabling a complete unauthenticated remote code execution chain.

Summary		(es) CentreStack antes de la versión 17.5 contiene una vulnerabilidad de clave criptográfica codificada de forma rígida que permite a atacantes no autenticados forjar tokens cifrados arbitrarios al explotar un valor SysNumber estático utilizado como entropía para AccessTicket.Encrypt() y AccessTicket.Decrypt() en todas las instalaciones. Los atacantes pueden usar la clave codificada de forma rígida para crear encabezados x-glad-auth válidos y llamar a puntos finales de API privilegiados como acquiretenantbackuptoken para obtener un IdentityTicket de administrador de dominio, lo que permite una cadena completa de ejecución remota de código no autenticada.
