(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."
