K-038: Security Holes in FileMaker 5 Web Companion

May 11, 2000 18:00 GMT


PROBLEM:       The field restriction "Don't show" may fail to prevent the
               exposure of the contents of data fields.
PLATFORM:      Only those platforms used to publish Filemaker 5 databases via
               the Web Companion.
DAMAGE:        Users may be able to gain unauthorized access to fields
               containing sensitive information.
SOLUTION:      Update Filemaker Pro 5 Web Companion as directed by the
               advisory.


VULNERABILITY Risk is MEDIUM. There has been discussion in public forums on ASSESSMENT: how to exploit the vulnerability.



The advisory below was captured on May 10, 2000 at the URL

FileMaker Web Companion Update 5.0v4
May 9, 2000

FileMaker Web Companion Update 5.0v4 WorldWide English.


Now available for download, FileMaker Pro 5 Web Companion 5.0v4
for FileMaker Pro 5, FileMaker Pro 5 Unlimited, and FileMaker
Developer 5.

The fix will be downloadable from www.filemaker.com/webcompanion.

The security issue is of concern only to FileMaker users publishing
FileMaker 5 databases via the Web Companion. We advise customers
who are using the FileMaker Pro 5 Web Companion to publish FileMaker
Pro 5 databases over the Web to install this update as soon as possible.

The fix addresses a Field-Level Security issue when using the Web
Security Database: Some technologies in the Web Companion may
inappropriately expose field contents which the user thinks are
protected by Field-Level Security.

This version supercedes 5.0v1, 5.0v2, 5.0v3 of the Web Companion.

Included with this update are:
1) Read Me
2) Web Companion 5.0v4

Select the platform version you wish to download: Mac | Windows
