Short explanation
CloudBeaver fails to consistently enforce global data export restrictions on certain server-side export operations (S0). This allows authenticated non-administrative users to initiate data exports even when administrators have disabled exports (S0).
This vulnerability can disclose database contents that the user is permitted to query but is not permitted to export (S0).
What should be done?
- Update to version 26.1.2 or later (S0)
- Follow vendor advisories (S0)
Chain of evidence and sources
CloudBeaver 26.1.1 ve önceki sürümlerde, sunucu tarafındaki dışa aktarım işlemleri global veri dışa aktarım kısıtlamasını tutarlı bir şekilde uygulamamaktadır.
Bu güvenlik açığı ek veritabanı okuma ayrıcalıkları sağlamaz, ancak yöneticiler devre dışı bırakmış olsa bile dışa aktarmaya izin verir.
Show the technical text from the sources
CloudBeaver is a cloud database manager. In versions up to and including 26.1.1, some server-side export operations do not consistently enforce the global data export restriction. An authenticated non-administrative user with access to a shared database connection can initiate certain server-side data exports even when an administrator has disabled exports. This can disclose database contents that the user is permitted to query but is not permitted to export. The issue does not grant additional database read privileges. It is fixed in 26.1.2 by consistently enforcing the global restriction for server-side exports.
