NVD · uneditedTablacus Explorer 17.3.30 and earlier allows arbitrary scripts to be executed in the context of the application due to specially crafted directory.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceTablacus Explorer 17.3.30 and earlier fails to properly sanitize directory names, allowing specially crafted directory names containing script content to be processed by the application.
