Title: Tarantella TTAWebTop.CGI Arbitrary File Viewing Vulnerability
Severity: HIGH
Description:
Tarantella Enterprise 3 is a tool for centralized management of data and applications. It is operated via a web interface. It will run on a number of Unix and Linux distributions.
ttawebtop.cgi is a CGI script included with the Tarantella, formerly SCO. ttawebtop.cgi is designed as management tool, designed to allow a user clicking a link to display and resume an application at any time.
A problem with the script makes it possible for remote users to gain access potentially sensitive files. This vulnerability allows remote users to view any file on the local system that is capable of being read by the webserver process.
The problem is in the validation of input by the script. The script allows a remote user to pass characters to the script which allows a user to traverse the directory structure. In doing so, it is possible for the user to read any file that's readable by the webserver process.
This problem can be exploited by a remote user in an information gathering attack, and could potentially lead to a remote user gaining local access to the affected system.
