Name of the Vulnerable Software and Affected Versions: TIBCO eFTL - Community Edition versions 6.5.0 and below TIBCO eFTL - Developer Edition versions 6.5.0 and below TIBCO eFTL - Enterprise Edition versions 6.5.0 and below

Description: The Windows Installation component of TIBCO Software Inc.'s TIBCO eFTL 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.

Recommendations: For TIBCO eFTL - Community Edition versions 6.5.0 and below, update to a version above 6.5.0 to resolve the issue. For TIBCO eFTL - Developer Edition versions 6.5.0 and below, update to a version above 6.5.0 to resolve the issue. For TIBCO eFTL - Enterprise Edition versions 6.5.0 and below, update to a version above 6.5.0 to resolve the issue. As a temporary workaround, consider restricting access to the Windows Installation component to minimize the risk of exploitation.
