Description:
Patrick has discovered a vulnerability in Icecast, which can be exploited by malicious people to disclose potentially sensitive information.
The vulnerability is caused due to an input validation error when handling HTTP requests for filenames with appended dots and white spaces. This can be exploited to disclose the source of arbitrary XSL Stylesheet (.xsl) files via a specially crafted request.
Example:
GET /auth.xsl. HTTP/1.0
The vulnerability has been confirmed in version 2.20 for Windows. Other versions may also be affected.
Solution:
Filter appended dots and white spaces in filenames in a proxy server or firewall with URL filtering capabilities.
