CVE-2023-31296
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedCSV Injection vulnerability in Sesami Cash Point & Transport Optimizer (CPTO) version 6.3.8.6 (#718), allows attackers to obtain sensitive information via the User Name field.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceCSV Injection vulnerability in Sesami Cash Point & Transport Optimizer allows attackers to inject malicious spreadsheet formulas (prefixed with =, +, -, @) into the User Name field. When administrators export user data to CSV and open it in spreadsheet software, these formulas can execute to exfiltrate sensitive information from the system.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the installed version of Sesami Cash Point & Transport OptimizerLocate the application version information in the software's about dialog, system information panel, or installation directory metadata. Compare it to the affected version 6.3.8.6.718.Affected if The installed version matches 6.3.8.6.718 exactly.
-
Verify access to the User Name field in user managementNavigate to the user creation or user profile management interface within the application and locate the User Name input field.Affected if The User Name field is accessible and accepts input without sanitization of special characters.
-
Confirm CSV export functionality existsLook for an export or data export feature in the administrative or user management section of the application that supports exporting user data to CSV format.Affected if A CSV export feature for user data is present and available to administrators.
-
Check for existing users with formula characters in namesQuery or list all existing user accounts and examine the User Name field for the presence of characters =, +, -, or @ at the beginning of the username.Affected if Any user account has a User Name starting with =, +, -, or @ characters.
You are affected if you are running version 6.3.8.6.718, have access to the User Name field, and possess a CSV export feature for user data, regardless of whether malicious usernames currently exist.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement input validation on the User Name field to strip or escape formula-special characters (=, +, -, @) and/or prefix all exported data with a single quote to neutralize formula execution in spreadsheet applications.
