Description

The remote host is affected by the vulnerability described in GLSA-200701-12 (Mono: Information disclosure)

Jose Ramon Palanco has discovered that the System.Web class in the XSP     for the ASP.NET server 1.1 through 2.0 in Mono does not properly     validate or sanitize local pathnames which could allow server-side file     content disclosure.

Impact :

An attacker could append a space character to a URI and obtain     unauthorized access to the source code of server-side files. An     attacker could also read credentials by requesting Web.Config%20 from a     Mono server.

Workaround :

There is no known workaround at this time.
