CVE-2026-14947Network attack vector

Authenticated arbitrary file write via ZIP traversal

Published Aug 20, 2026 · Updated Aug 20, 2026

Path traversal in Frauscher Sensortechnik FDS102 2.8.0 through 2.13.3 allows remote authenticated users to write files via crafted ZIP uploads. The ZIP upload workflow accepts archive entries containing ../ sequences and writes them to disk without constraining extraction paths to the intended directory. Exploitation requires high-privilege access to the web interface, but the resulting arbitrary file write on the server can be leveraged for code execution and full system compromise.
