Multiple vulnerabilities have been reported in Liferay Portal, which can be exploited by malicious users to disclose potentially sensitive information, conduct cross-site scripting and script insertion attacks, and potentially compromise a vulnerable system.
1) Input passed to the XSL Content Portlet is not properly verified before being used to display files. This can be exploited to disclose the contents of arbitrary XSL and XML files via the “file:///” path.
2) Certain unspecified input is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user’s browser session in context of an affected site.
3) Input passed via the title when creating a new message on the message board is not properly sanitised before being displayed on the search results page. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user’s browser session in context of an affected site when the malicious data is being viewed.
4) Certain unspecified input is not properly sanitised before being used by the XSL Content Portlet. This can be exploited to inject and execute arbitrary JSP code.
The vulnerabilities are reported in versions prior to 6.0.6.
