CVE-2024-43404Network attack vector

Remote code execution via math expression eval

Published Aug 20, 2024 · Updated Aug 20, 2024

Code injection in NicPWNs MEGABOT before 1.5.0 allows remote attackers to execute Python code through the Discord /math command. The math handler in commands/math.py passes the user-controlled expression parameter directly to Python eval(), treating code syntax as a calculation. Any Discord user who can invoke /math in a guild using the bot gains the bot process's execution privileges, exposing its data and availability.
