Title: Liferay Enterprise Portal User-Agent HTTP Header Cross Site Scripting Vulnerability
Severity: MODERATE
Description:
Liferay Enterprise Portal is a Java-based web portal for enterprises.
Liferay Enterprise Portal is prone to a cross-site scripting vulnerability because it fails to sufficiently sanitize user-supplied input to the 'Enterprise Admin Session Monitoring' portion of the application. Specifically, the application fails to sanitize the HTTP 'User-Agent' header, which allows remote attackers to inject arbitrary script code. Note that an attacker requires authentication to the portal to exploit this issue.
The attacker may leverage this issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may help the attacker steal cookie-based authentication credentials and launch other attacks.
This issue affects Liferay Enterprise Portal 4.3.6.
Affected Products:
- Liferay Enterprise Portal 4.3.6
