Description

Overview

Easynews does not adequately validate user input. Attackers may exploit this vulnerability to learn the filesystem path where the script is installed.

Description

Easynews is an open-source CGI script designed to create dynamic news story web pages and listings. Easynews does not properly filter input from an unspecified CGI variable. By setting the value of this variable to a non-number, an attacker can cause the script to crash and display the filesystem path where the script is installed.


Impact

An attacker can learn the filesystem path of the Easynews script, which includes the server's web directory.


Solution

The CERT/CC is currently unaware of a practical solution to this problem.
