PeopleSoft XML External Entities Vulnerability

Synopsis:

ISS X-Force has discovered a flaw in the PeopleSoft Application Messaging
Gateway. PeopleSoft enterprise software enables the management of all manner
of business functions, including human resources, customer relations, supply
chain, and finance. The PeopleSoft Application Messaging Gateway provides a
Web-based interface for PeopleSoft functionality and allows for communication
and synchronization between PeopleSoft products non-PeopleSoft products.

Impact:

The Application Messaging Gateway is configured to run by default on the
PeopleSoft Web server, and is accessible as a Java servlet. Attackers can use
an XML External Entities (XXE) attack to read any file on the vulnerable
PeopleSoft application server under the security context of the Web server
process. This attack may lead to the exposure of confidential information
stored in vulnerable PeopleSoft installations.

Affected Versions:

PeopleTools 8.1x prior to 8.19, included with most PeopleSoft installations,
including but not limited to:

PeopleSoft HCM (Human Capital Management)
PeopleSoft CRM (Customer Relationship Management)
PeopleSoft EPM (Enterprise Performance Management)
PeopleSoft FMS (Financial Management Solutions)
PeopleSoft SCM (Supply Chain Management)
PeopleSoft ESA (Enterprise Server Automation)
PeopleSoft SRM (Supplier Relationship Management)

Note: PeopleTools 8.4x is not vulnerable.
