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

Status and Recommendation (URLs may wrap): Ingres has issued the following patches to address the vulnerabilities. Ingres 2.6 Single-Byte patch - Ingres 2.6 Single-Byte patch ftp://ftp.ca.com/caproducts/ips/MDB/Generic_Ingres/IIS_Vulnerability/patch-2.6.0701.12467-win-x86.zip Ingres 2.6 Double-Byte patch- Ingres 2.6 Double-Byte patch ftp://ftp.ca.com/caproducts/ips/MDB/Generic_Ingres/IIS_Vulnerability/patch-2.6.0701.12473-win-x86-DBL.zip Ingres 2.5 Single Byte Patch- Ingres 2.5 Single Byte patch 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
