Descriptions

In BlackBerry QNX Software Development Platform (SDP) 6.6.0, an elevation of privilege vulnerability in the default configuration of the QNX SDP with QNet enabled on networks comprising two or more QNet nodes could allow an attacker to access local and remote files or take ownership of files on other QNX nodes regardless of permissions by executing commands targeting arbitrary nodes from a secondary QNX 6.6.0 QNet node.

En BlackBerry QNX Software Development Platform (SDP) 6.6.0, una vulnerabilidad de elevación de privilegios en la configuración por defecto del QNX SDP con QNet habilitado en redes formadas por dos o más nodos QNet podría permitir que un atacante acceda a archivos locales y remotos, así como a asumir la propiedad de archivos o de otros nodos QNX, independientemente de los permisos. Esto se logra ejecutando comandos que tengan como objetivo nodos arbitrarios de un nodo QNet QNX 6.6.0 secundario.
