Short explanation
Prior to version 2.4.0 of InvoiceShelf, a missing authorization check in POST /api/v1/estimates/{estimate}/convert-to-invoice creates an IDOR vulnerability allowing authenticated users to read and tamper with estimates from other companies.
This vulnerability compromises cross-company data security by allowing unauthorized users to copy, alter, or delete sensitive financial records and customer details belonging to different organizations.
What should be done?
- Update InvoiceShelf to version 2.4.0 or later
- Follow vendor advisory recommendations
Chain of evidence and sources
InvoiceShelf 2.4.0 öncesi sürümlerde, tahmin dönüştürme uç noktasında rota bağlı tahmin nesnesi için erişim yetkilendirmesi yapılmamaktadır.
Yetkilendirme eksikliği, kimliği doğrulanmış kullanıcıların başka bir şirketin tahmin verilerini kendi faturasına kopyalamasına olanak tanır.
Show the technical text from the sources
InvoiceShelf is an open-source web & mobile app that helps track expenses, payments and create professional invoices and estimates. Prior to version 2.4.0, POST /api/v1/estimates/{estimate}/convert-to-invoice in ConvertEstimateController authorizes only the caller's create-invoice ability and does not authorize access to the route-bound Estimate. Because route-model binding can resolve an estimate from any company, an authenticated user with create-invoice ability can copy another company's line items, prices, totals, taxes, notes, currency, and customer data into an invoice in the attacker's company. The victim company's configured conversion action reaches checkForEstimateConvertAction and can also change or delete the original estimate. This issue is fixed in version 2.4.0.
