Original release date: January 16, 2019
Last revised:
CVE-2018-18812
Source: TIBCO Software Inc.

Systems Affected

• TIBCO Spotfire Analytics Platform for AWS Marketplace versions 10.0.0 and below
• TIBCO Spotfire Server versions 7.10.1 and below
• TIBCO Spotfire Server versions 7.11.0, and 7.11.1
• TIBCO Spotfire Server versions 7.12.0, 7.13.0, 7.14.0, and 10.0.0

The following component is affected:

• Spotfire Library

Description

The component listed above contains a vulnerability that might theoretically fail to restrict users with read-only access from modifying files stored in the Spotfire Library, only when the Spotfire Library is configured to use external storage.

Impact

The impact of this vulnerability includes the theoretical possibility that a user with read-only access to the Spotfire Library can modify files stored in the Library. With that capability, among other possibilities, an attack could undermine the integrity of analysis results.

  CVSS v3 Base Score: 6.5 (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N)

Solution

TIBCO has released updated versions of the affected components which address these issues. In addition, we recommend that server administrators run the command line tool "check-external-library" to verify the consistency of the external storage. Please see the Spotfire Server Installation and Administration guide for further details.
