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. More information is available on the vendor's site at the following URL.
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.
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.
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.
iDefense confirmed the existence of this vulnerability in Altiris Deployment Solution for Windows version 6.8. The specific vulnerable executable is pxemtftp.exe version 6.8.8297.48.
If the PXE server component is not required in your environment it should be disabled.
