PeopleSoft PeopleTools Remote Command Execution Vulnerability
 
Synopsis:

ISS X-Force has discovered a flaw in the PeopleSoft PeopleTools application
framework. PeopleSoft enterprise software enables management of all manner of
business functions including human resources, customer relations, supply chain
and finance. The PeopleTools application framework includes a report
repository on the Web Server. The "SchedulerTransfer" Java servlet is used to
migrate reports to and from the report repository when using HTTP or HTTPS
transfer protocol. 

Impact:

The "SchedulerTransfer" servlet is configured to run by default on the
PeopleSoft Web server. It is accessible by unauthenticated users as a Java
servlet. Attackers could exploit a vulnerability to write arbitrary files with
attacker-defined data under the permissions of the Web server, leading to
remote command execution. This attack can result in complete compromise of
PeopleSoft Web Server installations.

Affected Versions:

PeopleTools 8.10-8.18, PeopleTools 8.40 and 8.41, 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 Service Automation)
PeopleSoft SRM (Supplier Relationship Management)
