Title: Icecast Server Directory Traversal Information Disclosure Vulnerability
Severity: MODERATE
Description:
Icecast is a freely available, open source streaming audio server. Icecast is available for the Unix, Linux, and Microsoft Windows platforms.
A directory traversal issue has been reported in some versions of Icecast server. It may be possible for a remote attacker to escape the web root and determine if a specific directory exists on the vulnerable server.
Reportedly, issuing an HTTP GET request for "/file/../../../../../../../../directory/" will return different results if the specified directory exists on the server filesystem. A '404 Not Found' response is received for a nonexistant directory, and an empty '200 OK' reponse indicates the specified directory exists.
An attacker may exploit this vulnerability to gather intelligence about the vulnerable system.
This issue may be related to a more severe directory traversal issue in earlier versions of Icecast, documented as BID 2932.
Affected Products:
- Caldera OpenLinux Server 3.1.0
- Caldera OpenLinux Server 3.1.1
- Icecast Icecast 1.3.12
