FKIE_CVE-2026-11429

Vulnerability from fkie_nvd - Published: 2026-06-05 22:16 - Updated: 2026-07-23 07:10
Severity
10.0 (Critical) - CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H
Summary
Two endpoints in the Vault Service ScriptsController, shared by Altium Enterprise Server and Altium 365, accept file uploads where a user-supplied filename component is used to construct the destination path without validation, allowing arbitrary files to be written to any location writable by the service account. Because the file write operation completes before authentication is validated, the vulnerability can be exploited without any credentials, session, or prior knowledge of the system. An unauthenticated network attacker can use this primitive to place executable content in directories where it is later executed by the service, resulting in remote code execution under the Vault Service account. Altium Enterprise Server is fixed in 8.1.1; the issue has been remediated in Altium 365 (commercial and government cloud) at the service level.

El servicio acepta una secuencia de operaciones de manipulaci\u00f3n de archivos post-clonaci\u00f3n que utilizan rutas proporcionadas por el usuario sin validaci\u00f3n, permitiendo a un usuario autenticado con acceso git b\u00e1sico mover archivos arbitrarios fuera del \u00e1rea de repositorio prevista.\n\nEsta primitiva de movimiento de archivos puede usarse para colocar contenido de script controlado por el atacante en directorios donde es ejecutado posteriormente por el servicio, resultando en ejecuci\u00f3n remota de c\u00f3digo bajo la cuenta del Servicio Git. En implementaciones multi-inquilino de Altium 365, esto podr\u00eda haber permitido el acceso a datos pertenecientes a otros inquilinos en el mismo nodo de infraestructura. Altium Enterprise Server est\u00e1 corregido en 8.1.1; el problema ha sido remediado en Altium 365 a nivel de servicio."
