Description

Vulnerability Description

Sambar Server contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate pkg variables upon submission to the showfnc.stm script. This could allow a user to create a specially crafted URL that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.

Solution Description

Upgrade to version 6.0 beta 1 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
