Gentoo Linux Security Advisory

Title: Mono: Information disclosure (GLSA 200701-12)
Severity: low
Exploitable: remote
Date: January 16, 2007
Updated: January 17, 2007
Bug(s): #159886
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: dev-lang/mono
Vulnerable: < 1.2.2.1
Unaffected: >= 1.2.2.1
Architectures: 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:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-lang/mono-1.2.2.1"


References

CVE-2006-6104
