Symantec Altiris Deployment Solution TFTP/MTFTP Service Directory
Traversal Vulnerability
------------------------------------------------------------------------

SUMMARY

<http://www.altiris.com/Products/DeploymentSolution.aspx> Symantec
Altiris Deployment Solution is "an automated OS deployment solution that
is used for deploying and managing servers, desktops, and notebooks from a
central location". Remote exploitation of a directory traversal
vulnerability in Symantec's Altiris Deployment Solution products could
allow attackers to gain read access to arbitrary files hosted on the
Altiris server.

DETAILS

Vulnerable Systems:
* Altiris Deployment Solution for Windows version 6.8 (pxemtftp.exe

version 6.8.8297.48)

Immune Systems:
*

Altiris Deployment Solution includes a tftp/mtftp server within its
optional PXE server component which suffers from a directory traversal
condition. The server runs with SYSTEM level privileges and allows
unauthenticated attackers to download any file on the system.

Analysis:
Exploitation allows attackers to read arbitrary files from the server
machine. The tftp/mftp daemon runs with SYSTEM level privileges, so any
file readable by SYSTEM with a known file path can be downloaded without
authentication.

Workaround:
If the PXE server component is not required in your environment it should
be disabled.

Vendor response:
Symantec Altiris has addressed this vulnerability by releasing a HotFix.
