I. Advisory
Background: Cross-Site Scripting (XSS) vulnerabilities are well documented in the industry. XSS vulnerability requires three parties:
- A susceptible Web site.
- A valid user of the Web site.
- An attacker.
The attacker tricks the user (usually via misleading links on web pages or emails) to exploit the XSS vulnerability in the Web site. This allows the attacker to run arbitrary client-side (i.e. browser) scripts that execute as the identity of the valid user. Typically this is used to steal session cookies thereby allowing the attacker to impersonate the valid user. XSS vulnerabilities can arise due to bugs in the Web server or in applications running on it.
BEA AquaLogic Interaction 6.1 and BEA Plumtree Foundation 6.0 are vulnerable to a cross site scripting (XSS) vulnerability affecting all portal applications.
This advisory corrects this issue by providing patches that are required to secure a portal to prevent a cross site scripting attack.
