CVE-2021-38180Network attack vector

Authenticated command execution via unsanitized spreadsheet formulas

Published Oct 12, 2021 · Updated Aug 4, 2024

CSV injection in SAP Business One before 10.0 allows remote authenticated users to execute commands through exported spreadsheet formulas. The Excel/CSV export routine writes attacker-controlled cell content without neutralizing formula-leading characters, causing Excel to interpret the content as a formula. Execution requires a victim to open the exported file, enable macros, and use Excel security settings that permit command execution.
