Title: [CAID 35970]: CA Products That Embed Ingres Authentication
Vulnerability

CA Vuln ID (CAID): 35970

CA Advisory Date: 2007-12-19

Reported By: Ingres Corporation

Impact: Attacker can gain elevated privileges.

Summary: A potential vulnerability exists in the Ingres software
that is embedded in various CA products. This vulnerability exists
only on Ingres 2.5 and Ingres 2.6 on Windows, and does not
manifest itself on any Unix platform. Ingres r3 and Ingres 2006
are not affected. The vulnerability, CVE-2007-6334, is associated
with users who connect after the first user being assigned the
privileges and identity of the first user. In all reported
instances, the application (typically an ASP.NET application using
the Ingres ODBC driver) was running on Microsoft IIS Web server,
and with the Integrated Windows Authentication (IWA) option
enabled. While IWA is not enabled by default, it is a commonly
used option. It should be noted that the Ingres .NET data provider
is not affected.

Mitigating Factors: The vulnerability exists only on Windows
systems running Microsoft IIS Web server that have the Integrated
Windows Authentication (IWA) option enabled.

Severity: CA has given this vulnerability a High risk rating.

Affected Products:
All CA products that embed Ingres 2.5 and Ingres 2.6, and also run
Microsoft IIS Web server with the Integrated Windows
Authentication (IWA) option enabled.

Affected Platforms:
Windows

vulnerabilities.

ftp://ftp.ca.com/caproducts/ips/MDB/Generic_Ingres/IIS_Vulnerability/patch-
2.5.0605.12291-win-x86.zip
Potential problems installing the patches:
While testing these patches, CA identified an install issue when
the user is presented with the option to make a backup of the
Ingres installation. In cases where a <space> is in the path, the
path is not properly read. The backup does get taken and is by
default stored in the %II_SYSTEM%\ingres\install\backup directory.
Additionally, if the user happens to press the "Set Directory"
button, the path will be displayed. Clicking "ok" will result in a
message stating "... spaces are not supported in paths... ". This
also is an error; pressing cancel will return the user to the
first screen with the default path, and while the displayed path
is terminated at a space, the actual path does work. To avoid this
issue, use DOS 8.3 definitions (ex. C:\progra~1\CA\ingres).

How to determine if you are affected:
Check the %II_SYSTEM%\ingres\version.rel file to identify the
Ingres version. If the installed version of Ingres 2.6 is a
Double-Byte version (should have DBL referenced), please download
the 2.6 Double-Byte patch. Otherwise, use the Single-Byte patch.

Workaround: None
