Source: TIBCOSoftware Inc.

Products Affected

TIBCO PartnerExpress versions 6.2.1 and below

The following components are affected:

• Interior Server
• Gateway Server

Description

The components listed above contain easily exploitable Stored and Reflected
Cross Site Scripting (XSS) vulnerabilities that allow a low privileged
attacker to social engineer a legitimate user with network access to execute
scripts targeting the affected system or the victim’s local system. A
successful attack using this vulnerability requires human interaction from a
person other than the attacker.

Impact

In the worst case, if the victim is a privileged administrator, successful
execution of these vulnerabilities can result in an attacker gaining full
administrative access to the affected system or the victim’s local system.
