CVE-2025-12418

System interruption via symlink-following uninstaller deletion

Published Nov 7, 2025 · Updated Nov 7, 2025

Link following in affected Revenera InstallShield releases allows local users to cause a service interrupt during Suite uninstallation. The Suite uninstaller removes a user-writable configuration directory after resolving an attacker-controlled symbolic link, causing deletion to follow the link to an unintended target. Exploitation requires local users to prepare the link and an administrator to run the affected uninstall path; successful abuse deletes unintended files and can interrupt the system.
