-- Corsaire Security Advisory -- Title: PeopleSoft Gateway Administration servlet path disclosure issue Date: 04.07.03 Application: PeopleTools 8.20/8.43 and prior Environment: Various Author: Martin O'Neal [martin.oneal () corsaire com] Audience: General distribution Reference: c030704-003 -- Scope -- The aim of this document is to clearly define a vulnerability in the PeopleSoft Gateway Administration servlet, as supplied by PeopleSoft Ltd. [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. In the event of an invalid value being entered, the actual path of the server side configuration files is disclosed in the error response. -- Analysis -- The gateway.administration servlet is used within the PeopleSoft environment 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. Release Patch 8.18 8.18.15 8.19 8.19.12 8.20 8.20.03 8.42 8.42.14 8.43 8.43.11 For those who can not implement the patches promptly, as a mitigating strategy a firewall or other HTTP filtering device can be used to block queries containing sensitive strings, or as a last resort the administration functionality of the PeopleSoft Gateway can be disabled by restricting access to the servlet itself. -- CVE -- The Common Vulnerabilities and Exposures (CVE) project has assigned the name CAN-2003-0628 to this issue. This is a candidate for inclusion in the CVE list (http://cve.mitre.org), which standardises names for security problems. -- References -- [1] http://www.peoplesoft.com [2] http://www.peoplesoft.com/corp/en/patch_fix/search.jsp -- Revision -- a.
