Name of the Vulnerable Software and Affected Versions LimeSurvey versions 2.0 through 2.06+ Build 151014

Description An unauthenticated file download issue exists in the application. The application does not validate serialized input to the admin backup endpoint (index.php/admin/update/sa/backup), allowing attackers to specify arbitrary file paths using a crafted datasupdateinfo payload. This can lead to the ability to read arbitrary files on the host system, including sensitive OS and configuration files.

Recommendations LimeSurvey versions 2.0 through 2.06+ Build 151014: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
