imx6 bundle: Improper Neutralization of Formula Elements in a CSV File
CVE-2023-45597 is a critical-severity improper neutralization of formula elements in a CSV file vulnerability in imx6 bundle from AiLux, with a CVSS 3.1 base score of 9.0 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, but only if a user takes part, for example by opening a link or file. The record lists version 1.0.7-2 as the first without the flaw, so updating imx6 bundle to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.45% chance of exploitation within 30 days, which is low compared with other CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update imx6 bundle to 1.0.7-2 or a later version.
- Update Imx6 to 1.0.7-2 or a later version.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

Official description
A CWE-1236 “Improper Neutralization of Formula Elements in a CSV File” vulnerability in the “file_configuration” functionality of the web application (concerning the function “export_file”) allows a remote authenticated attacker to inject arbitrary formulas inside generated CSV files. This issue affects: AiLux imx6 bundle below version imx6_1.0.7-2.

The underlying weakness: Improper Neutralization of Formula Elements in a CSV File
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.
How developers prevent this class of flaw
- 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).
- If a field starts with a formula character, prepend it with a ' (single apostrophe), which prevents Excel from executing the formula.
- 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.
