| Date: | 01/16/2007 |
| Bugs: | |
| ID: | 200701-12 |
Synopsis
Mono does not properly sanitize pathnames allowing unauthorized information disclosure.Background
Mono provides the necessary software to develop and run .NET client and server applications on various platforms.
Affected packages
| Package | Vulnerable | Unaffected | Architecture(s) |
|---|---|---|---|
| dev-lang/mono | < 1.2.2.1 | >= 1.2.2.1 | All supported architectures |
Description
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.
Resolution
All Mono users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-lang/mono-1.2.2.1"
