Mitigation
When 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).
Mitigation
If a field starts with a formula character, prepend it with a ' (single apostrophe), which prevents Excel from executing the formula.
Mitigation
Certain 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.
No CAPEC attack patterns related to this CWE.
