CVE-2024-11800

Code execution via V8 parser stack overflow

Published Nov 27, 2024 · Updated Nov 29, 2024

Stack-based buffer overflow in Fuji Electric TELLUS Lite 4.0.20.0 allows remote attackers to execute code via a crafted V8 file. The V-Simulator 5 parser copies attacker-controlled data into a fixed-length stack buffer without first validating its length. Exploitation requires a user to visit a malicious page or open the file, after which code runs in the context of the current process.
