CVE-2019-17334

The Visualizations component of TIBCO Software Inc.s TIBCO Spotfire Analyst, TIBCO Spotfire Analytics Platform for AWS Marketplace, TIBCO Spotfire Deployment Kit, TIBCO Spotfire Desktop, and TIBCO Spotfire Desktop Language Packs contains a vulnerability that theoretically allows an attacker with permission to write DXP files to the Spotfire library to remotely execute code of their choice on the user account of other users who access the affected system. This attack is a risk only when the attacker has write access to a network file system shared with the affected system. Affected releases are TIBCO Software Inc.s TIBCO Spotfire Analyst: versions 7.11.1 and below, versions 7.12.0, 7.13.0, 7.14.0, 10.0.0, 10.1.0, 10.2.0, 10.3.0, 10.3.1, and 10.3.2, versions 10.4.0, 10.5.0, and 10.6.0, TIBCO Spotfire Analytics Platform for AWS Marketplace: version 10.6.0, TIBCO Spotfire Deployment Kit: versions 7.11.1 and below, TIBCO Spotfire Desktop: versions 7.11.1 and below, versions 7.12.0, 7.13.0, 7.14.0, 10.0.0, 10.1.0, 10.2.0, 10.3.0, 10.3.1, and 10.3.2, versions 10.4.0, 10.5.0, and 10.6.0, and TIBCO Spotfire Desktop Language Packs: versions 7.11.1 and below.

Potential Mitigations

• Compartmentalize the system to have “safe” areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
• Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
