[1], that allows an attacker to disclose the actual path of server configuration files. - -- History -- Discovered: 01.07.03 (Martin O'Neal) Vendor notified: 04.07.03 Document released: 12.11.03 - -- Overview -- The PeopleSoft Gateway Administration servlet provides a web-based interface to configure handlers.

This application accepts a number of values via an HTML form. If an invalid value is entered, then the servlet responds with an error page that contains the actual path of the server side configuration files. This path can then be used in conjunction with other potential vulnerabilities to attack specific OS and application configuration files. - -- Recommendations -- PeopleSoft have released details of this and other issues under security rollup vulnerability ID 20031112, which is available to registered users from the PeopleSoft support site [2]. PeopleSoft recommends that customers address the vulnerability by applying the following fixes available on PeopleSoft Customer Connection.
