Hiện thực hóa · Hiệu quả: KháWhen generating CSV output, ensure that formula-sensitive metacharacters are effectively escaped or removed from all data before storage in the resultant CSV. Risky characters include '=' (equal), '+' (plus), '-' (minus), and '@' (at).Unfortunately, there is no perfect solution, since different spreadsheet products act differently.
Hiện thực hóa · Hiệu quả: KháIf a field starts with a formula character, prepend it with a ' (single apostrophe), which prevents Excel from executing the formula.It is not clear how effective this mitigation is with other spreadsheet software.
Kiến trúc và thiết kế · Hiệu quả: Hạn chếCertain implementations of spreadsheet software might disallow formulas from executing if the file is untrusted, or if the file is not authored by the current user.This mitigation has limited effectiveness because it often depends on end users opening spreadsheet software safely.

Phương pháp	Cách làm	Hiệu quả
Phân tích tĩnh tự động	Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)	Cao
