CVE-2026-54363

Gladinet / CentreStack

9.3 · CVSS 4.0Critical

Description

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.
