                       AIX Anonymous FTP Vulnerability

- ---------------------------------------------------------------------------

The Computer Emergency Response Team/Coordination Center (CERT/CC) has

received information concerning a vulnerability in the anonymous FTP

configuration in all versions of AIX.

IBM is aware of this problem and a fix is available as apar number

"ix23944".  This patch is available for all AIX releases from "GOLD".

IBM customers may call IBM Support (800-237-5511) and ask that the fix

be shipped to them.  Patches may be obtained outside the U.S. by contacting 

your local IBM representative.  The fix will appear in the upcoming 2009 

update and the next release of AIX.

I.   Description

     Previous versions of the anonymous FTP installation script,

     /usr/lpp/tcpip/samples/anon.ftp, incorrectly configured various files

     and directories.


II.  Impact

     Remote users can execute unauthorized commands and gain access to the

     system if anonymous FTP has been installed.

III. Solution

     A.  Obtain the fix from IBM Support.  The fix contains three

         files: a "readme" file (README.a23944), the fix installation

         script (install.a23944), and an archive containing the updated

         files (PATCH.a23944.Z).

     B.  Install the fix following the instructions in the README file.

The CERT/CC would like to thank Charles McGuire of the Computer Science

Department, the University of Montana for bringing this security

vulnerability to our attention and IBM for their response to the problem.
