CVE-2023-38843Public exploitNetwork attack vector

Authenticated code execution via CSV formula injection

Published Aug 17, 2023 · Updated Oct 8, 2024

CSV formula injection in Atlos 1.0 allows remote authenticated users to execute arbitrary code through a crafted incident description. The incident export preserves a formula-leading description as an executable spreadsheet cell instead of neutralizing it. Execution requires another user to export the incident data and open the resulting CSV in formula-capable spreadsheet software.
