CVE-2018-25135Public exploit

Command execution via unneutralized spreadsheet formulas

Published Dec 24, 2025 · Updated Dec 24, 2025

CSV injection in Anviz CrossChex Standard 4.3.6.0 allows attackers to execute commands through crafted user import fields. The import/export workflow sends formula-prefixed Name, Gender, Position, and other user fields to Excel without neutralization, causing Excel to evaluate the payload. Execution requires an operator to import or export attacker-controlled user data on a Windows host with Excel, and commands run in that operator's context.
