CVE-2024-23622Network attack vector

SYSTEM code execution via CopySLS_Request3 stack overflow

Published Jan 25, 2024 · Updated Jun 17, 2025

Stack-based buffer overflow in the eFilm Workstation 4.1 through 4.2 license server allows remote attackers to execute code as SYSTEM. The published record identifies CopySLS_Request3 and an incorrect stack-buffer size calculation, but does not disclose the affected buffer or copy operation. No authentication or user interaction is required, and successful exploitation grants SYSTEM-level control of the license-server host.
