Published Mar 11, 2009
·
Updated

The NFS server in Sun Solaris 10, and OpenSolaris before snv111, does not properly implement the AUTHNONE (aka sec=none) security mode in combination with other security modes, which allows remote attackers to bypass intended access restrictions and read or modify files, as demonstrated by a combination of the AUTHNONE and AUTHSYS security modes.
