Name of the Vulnerable Software and Affected Versions Symantec Messaging Gateway versions prior to 10.6.2

Description The issue allows remote authenticated users to read arbitrary files. This is achieved by exploiting a directory traversal vulnerability in the charting component. The vulnerability can be triggered by including a .. (dot dot) in the sn parameter to the "brightmail/servlet/com.ve.kavachart.servlet.ChartStream" endpoint.

Recommendations For versions prior to 10.6.2, update to version 10.6.2 or later to resolve the issue. As a temporary workaround, consider restricting access to the brightmail/servlet/com.ve.kavachart.servlet.ChartStream endpoint to minimize the risk of exploitation. Avoid using the sn parameter in the affected endpoint until the issue is resolved.
