CVE-2023-42138

Information disclosure via out-of-bounds read

Published Oct 11, 2023 · Updated Sep 18, 2024

Out-of-bounds read in KEYENCE KV STUDIO 11.62 and earlier allows attackers to disclose information or execute code via a crafted file opened by a user. The vulnerable parser reads beyond a valid buffer while processing specially crafted project or replay data. Exploitation requires a user to open the file in KV STUDIO PLAYER, so impact depends on successful user interaction and can include disclosure or arbitrary code execution.
