FKIE_CVE-2026-77767
Vulnerability from fkie_nvd - Published: 2026-08-21 11:17 - Updated: 2026-10-16 15:10
Severity
Summary
Reconmap's API applies a fallback authorization policy in apps/api/app/Program.cs that requires an authenticated user holding the administrator role, so controllers without their own attribute reject anonymous callers. The report preview action in apps/api/app/Controllers/ReportsController.cs carries [AllowAnonymous] and therefore opts out of that policy. PreviewReport loads the Project row named by the id path segment, loads the linked Organisation through the project's ClientId, and renders both into default-report-template.html, which prints the project name and description together with the client organisation's name, address and URL. No authentication, project membership or role check is performed. Because the id is the auto-increment primary key of the project table, an unauthenticated remote caller can walk sequential ids to retrieve the engagement details and client organisation of every project on the instance, and the 404 returned for a missing id reveals which project ids exist. Reconmap stores penetration-testing engagements, so the disclosed descriptions and client records are sensitive by nature.

"value": "La API de Reconmap aplica una pol\u00edtica de autorizaci\u00f3n de respaldo en apps/api/app/Program.cs que requiere un usuario autenticado que posee el rol de administrador, por lo que los controladores sin su propio atributo rechazan a los llamadores an\u00f3nimos. La acci\u00f3n de vista previa de informe en apps/api/app/Controllers/ReportsController.cs lleva [AllowAnonymous] y por lo tanto se excluye de esa pol\u00edtica. PreviewReport carga la fila de Proyecto nombrada por el segmento de ruta \u0027id\u0027, carga la Organizaci\u00f3n vinculada a trav\u00e9s del ClientId del proyecto, y renderiza ambos en default-report-template.html, que imprime el nombre y la descripci\u00f3n del proyecto junto con el nombre, la direcci\u00f3n y la URL de la organizaci\u00f3n del cliente. No se realiza ninguna autenticaci\u00f3n, verificaci\u00f3n de membres\u00eda de proyecto o de rol. Debido a que el \u0027id\u0027 es la clave primaria de auto-incremento de la tabla de proyectos, un llamador remoto no autenticado puede recorrer IDs secuenciales para recuperar los detalles del compromiso y la organizaci\u00f3n del cliente de cada proyecto en la instancia, y el 404 devuelto por un \u0027id\u0027 faltante revela qu\u00e9 IDs de proyecto existen. Reconmap almacena compromisos de pruebas de penetraci\u00f3n, por lo que las descripciones divulgadas y los registros de clientes son sensibles por naturaleza."
