Achievo-1.3.2-STABLE Cross Site Scripting (XSS)

---------------------------------------------------
Advisory:
Achievo-1.3.2-STABLE Cross Site Scripting (XSS).

Version Affected:
Achievo-1.3.2-STABLE

Release Date:
19 September 2008

Background:
Cross site scripting (also referred to as XSS) is a vulnerability that allows an attacker to send malicious code (usually in the form of Javascript) to another user. Because a browser cannot know if the script should be trusted or not, it will execute the script in the user context allowing the attacker to access any cookies or session tokens retained by the browser.

Description:
Malicious users may inject JavaScript, VBScript, ActiveX, HTML or Flash into a vulnerable application to fool a user in order to gather data from them. An attacker can steal the session cookie and take over the account, impersonating the user. It is also possible to modify the content of the page presented to the user.
