NSF File Access Vulnerability

## NFS File Access Vulnerability

### Risk Factor: 8

### Machines Affected:

Most unpatched, misconfigured, older NFSs

### Description:

NFS Access Files are files that would lead to higher access that are exported and in a writeable directory. An intruder could possibly modify these files to gain access to the machine. Note: This does not indicate that the export is read-writeable but that the directory on the file system has writeable permission.

### Consequences:

Anyone mounting the drive can alter files and create files in order to gain higher access priveledges, even possibly root priviledges.

### Fix:

Ensure that these files and export directories are not accessible by unauthorized hosts through proper NFS export lists. Obviously, don't leave SUID scripts lieing around.
