Technical details

A CSV Injection (Formula Injection) vulnerability exists in the 'create_supplier' function within the '/Export_csv/export' component of SourceCodester Pharmacy Sales and Inventory System v1.0. The application fails to sanitize user-supplied input in fields such as 'Address' and 'Company Name' before including them in CSV exports. An attacker with high privileges (PR:H) can inject spreadsheet formulas (starting with =, +, -, or @). When an administrator exports the supplier list and opens it in a spreadsheet application like Microsoft Excel or WPS Spreadsheet, these formulas execute. This can be used for data exfiltration via HYPERLINK functions or potential remote command execution depending on the spreadsheet environment. A public exploit (PoC) has been disclosed.
