CWE-1236

Allowed

Improper Neutralization of Formula Elements in a CSV File

Abstraction: Base · Status: Incomplete

The product saves user-provided information into a Comma-Separated Value (CSV) file, but it does not neutralize or incorrectly neutralizes special elements that could be interpreted as a command when the file is opened by a spreadsheet product.

429 vulnerabilities reference this CWE, most recent first.

CVE-2024-9102 (GCVE-0-2024-9102)

Title
phpLDAPadmin: Improper Neutralization of Formula Elements
Summary
phpLDAPadmin since at least version 1.2.0 through the latest version 1.2.6.7 allows users to export elements from the LDAP directory into a Comma-Separated Value (CSV) file, but it does not neutralize special elements that could be interpreted as a command when the file is opened by a spreadsheet product. Thus, this could lead to CSV Formula Injection. NOTE: This vulnerability will not be addressed, the maintainer's position is that it is not the intention of phpLDAPadmin to control what data Administrators can put in their LDAP database, nor filter it on export.

Title
iTop vulnerable to potential formula injection in Excel/CSV export file
Summary
iTop is an IT service management platform. When exporting data from backoffice or portal in CSV or Excel files, users' inputs may include malicious formulas that may be imported into Excel. As Excel 2016 does **not** prevent Remote Code Execution by default, uninformed users may become victims. This vulnerability is fixed in 2.7.9, 3.0.4, 3.1.1, and 3.2.0.

Mitigation
Implementation

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
Implementation

If a field starts with a formula character, prepend it with a ' (single apostrophe), which prevents Excel from executing the formula.

Mitigation
Architecture and Design

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.
