Software vulnerable: Snapstream PVS
Vendor website: http://www.snapstream.com
Workaround: Stop the snapstream server

Software synopsis:
Snapstream PVS is a Personal Video System for Windows Systems. It allows users to schedule recordings on their PC and to view them later at the leisure, at their local machine or across a TCP/IP network via an HTTP interface.

Typically, the Snapstream HTTP interface runs on TCP port 8129.

Problem description:

Issue 1: Directory traversal bug

It is possible to navigate outside of the HTTP base directory, and download any file from the host for which the filename is known. The HTTP server runs in the context of the logged in user.

Examples:

http://home.victim.com:8080/../../../../autoexec.bat

http://home.victim.com:8080/../../../winnt/repair/sam

Risk: High. Any files on the target system are available to an attacker.

Issue 2: SSD.ini, which contains a great deal of information regarding the target system can be retrieved remotely using the method detailed above.

Example:

http://home.victim.com:8080/../ssd.ini

Risk: High. Information included in the ini file includes base directory location, usernames, and passwords.

Issue 3: Passwords are stored as plaintext in SSD.INI

Passwords to the SnapStream PVS software are recoverable remotely using the method detailed in Issue 2.

Risk: High. Denial of service, destruction of data, exposure of passwords.
