Descriptions

An issue was discovered in OpenAFS before 1.6.23 and 1.8.x before 1.8.2. The backup tape controller (butc) process accepts incoming RPCs but does not require (or allow for) authentication of those RPCs. Handling those RPCs results in operations being performed with administrator credentials, including dumping/restoring volume contents and manipulating the backup database. For example, an unauthenticated attacker can replace any volume's content with arbitrary data.

Se ha descubierto un problema en OpenAFS, en versiones anteriores a la 1.6.23 y versiones 1.8.x anteriores a la 1.8.2. El proceso butc (backup tape controller) acepta los RPC entrantes, pero no requiere (ni permite) la autenticación de dichos RPC. El manejo de los RPC resulta en que las operaciones se realizan con credenciales de administrador, incluyendo el contenido de los volúmenes dumping/restoring y en que se manipula la base de datos de backups. Por ejemplo, un atacante no autenticado puede reemplazar el contenido de cualquier volumen con datos arbitrarios.
