The Windows Installation component of TIBCO Software Inc.s TIBCO Enterprise Runtime for R - Server Edition, TIBCO Enterprise Runtime for R - Server Edition, TIBCO Enterprise Runtime for R - Server Edition, TIBCO Spotfire Analytics Platform for AWS Marketplace, TIBCO Spotfire Server, TIBCO Spotfire Server, TIBCO Spotfire Server, TIBCO Spotfire Statistics Services, TIBCO Spotfire Statistics Services, and TIBCO Spotfire Statistics Services contains a vulnerability that theoretically allows a low privileged attacker with local access on some versions of the Windows operating system to insert malicious software. The affected component can be abused to execute the malicious software inserted by the attacker with the elevated privileges of the component. This vulnerability results from a lack of access restrictions on certain files and/or folders in the installation. Affected releases are TIBCO Software Inc.s TIBCO Enterprise Runtime for R - Server Edition: versions 1.2.4 and below, TIBCO Enterprise Runtime for R - Server Edition: versions 1.3.0 and 1.3.1, TIBCO Enterprise Runtime for R - Server Edition: versions 1.4.0, 1.5.0, and 1.6.0, TIBCO Spotfire Analytics Platform for AWS Marketplace: versions 11.3.0 and below, TIBCO Spotfire Server: versions 10.3.12 and below, TIBCO Spotfire Server: versions 10.4.0, 10.5.0, 10.6.0, 10.6.1, 10.7.0, 10.8.0, 10.8.1, 10.9.0, 10.10.0, 10.10.1, 10.10.2, 10.10.3, and 10.10.4, TIBCO Spotfire Server: versions 11.0.0, 11.1.0, 11.2.0, and 11.3.0, TIBCO Spotfire Statistics Services: versions 10.3.0 and below, TIBCO Spotfire Statistics Services: versions 10.10.0, 10.10.1, and 10.10.2, and TIBCO Spotfire Statistics Services: versions 11.1.0, 11.2.0, and 11.3.0.

Weakness

The product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors.

Potential Mitigations

  • Run the code in a “jail” or similar sandbox environment that enforces strict boundaries between the process and the operating system. This may effectively restrict which files can be accessed in a particular directory or which commands can be executed by the software.
  • OS-level examples include the Unix chroot jail, AppArmor, and SELinux. In general, managed code may provide some protection. For example, java.io.FilePermission in the Java SecurityManager allows the software to specify restrictions on file operations.
  • This may not be a feasible solution, and it only limits the impact to the operating system; the rest of the application may still be subject to compromise.
  • Be careful to avoid CWE-243 and other weaknesses related to jails.
