Icecast Server Slash File Name Denial Of Service Vulnerability
Icecast is an open source audio-streaming server for both Unix and Microsoft Windows systems. Icecast does not sufficiently sanitize user-supplied input, or sanely handle unexpected input. Upon receiving a request from a user for a file that ends with a slash or period, the server will crash. The behaviour occurs when the remote attacker adds an '/', '\' or '.' to the end the URL they craft to request the file. The request of an existing file is not necessary, as the Icecast server will fail regardless. |
