CVE-2023-29918Public exploitNetwork attack vector

Spreadsheet formula execution via unneutralized Periods export

Published May 2, 2023 · Updated Jan 30, 2025

CSV injection in the Periods Module in RosarioSIS 10.8.4 allows remote authenticated users to inject formulas into exported spreadsheet data. Public records identify the module and weakness but do not disclose the affected field, export routine, or exact failure to neutralize formula-leading input. Exploitation requires low-privileged access and a user to open the crafted export in spreadsheet software, enabling formula-driven data access or modification.
