Bug vulnerability class | Denial Of Service |
Bug description | The remote server runs a version of ICECast, an open source streaming audio server, which is older than version 1.3.12. This version is affected by a remote denial of service because Icecast server does not properly sanitize user-supplied input. An remote attacker could send specially crafted URL, by adding '/', '\' or '.' to the end, that may result in a loss of availability for the service. |
Bug solution | Upgrade the software to the latest version. The server should be deactivated or de-installed if not necessary. To make it harder to find the server the daemon could be configured to listen at another port (e.g. 8081). Try to prevent unwanted connection attempts by filtering traffic with firewalling. Alternation of the application banner can confuse an attacker and let him determine the wrong software. |
