CVE-2024-27144Public exploitNetwork attack vector

Remote code execution via traversal-based file upload

Published Jun 14, 2024 · Updated Feb 13, 2025

Path traversal in Toshiba Tec e-STUDIO TopAccess allows remote attackers to overwrite executable files through unauthenticated uploads. The upload handler accepts traversal sequences in multipart file names and writes attacker-controlled content outside the intended storage directory. Replacing Python modules, startup programs, or shared libraries enables code execution as Apache or root when the overwritten component loads.
