Summary
Tendenci is Vulnerable to CSV Formula Injection through its Contact Form Message Field
Details

Tendenci 12.3.1 contains a CSV formula injection vulnerability in the contact form message field that allows attackers to inject malicious formulas during export. Attackers can submit crafted payloads like '=10+20+cmd|' /C calc'!A0' in the message field to trigger arbitrary command execution when the CSV is opened in spreadsheet applications.

Details

In “SuiteCRM” application, v7.11.18 through v7.11.19 and v7.10.29 through v7.10.31 are affected by “CSV Injection” vulnerability (Formula Injection). A low privileged attacker can use accounts module to inject payloads in the input fields. When an administrator access accounts module to export the data as a CSV file and opens it, the payload gets executed. This was not fixed properly as part of CVE-2020-15301, allowing the attacker to bypass the security measure.

The AnWP Football Leagues plugin for WordPress is vulnerable to CSV Injection in all versions up to, and including, 0.16.17 via the 'download_csv_players' and 'download_csv_games' functions. This makes it possible for authenticated attackers, with Administrator-level access and above, to embed untrusted input into exported CSV files, which can result in code execution when these files are downloaded and opened on a local system with a vulnerable configuration.

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.

No CAPEC attack patterns related to this CWE.
