Upgrading to version 1.5.1.7 is able to mitigate this issue. The affected component should be upgraded. The vendor recommends: "1.5.1.6 isn't the latest version of 2960, the latest version fixes many security issues. And we have another one in our release plan which should solve the issues reported."
