CVE-2023-50254Public exploit

Code execution via symlinked DOCX conversion output

Published Dec 22, 2023 · Updated Aug 2, 2024

Path traversal in Deepin Reader before 6.0.7 allows context-dependent attackers to execute code through a crafted DOCX file. DocumentFactory extracts the archive, then directs pandoc to write a fixed word/temp.html path without rejecting an archive-supplied symbolic link. The user must open the document, and execution occurs after the overwritten shell startup file is loaded by opening a terminal.
