CVE-2023-47580

Code execution and disclosure via malformed file parsing

Published Nov 15, 2023 · Updated Aug 14, 2024

Memory-boundary errors in Fuji Electric TELLUS and TELLUS Lite 4.0.17.0 and earlier allow local users to execute code via crafted files. The products mishandle memory while parsing crafted X1, V8, or V9 files, but Fuji Electric has not published the affected parser routines or exact invalid operations. Exploitation requires a user to open the file and can expose process-accessible information or execute code in that user's application context.
