In Apache CloudStack improper control of generation of code ('Code Injection') vulnerability is found in the following APIs which are accessible only to admins.
* quotaTariffCreate
* quotaTariffUpdate
* createSecondaryStorageSelector
* updateSecondaryStorageSelector
* updateHost
* updateStorage
This issue affects Apache CloudStack: from 4.18.0 before 4.20.2, from 4.21.0 before 4.22.0. Users are recommended to upgrade to versions 4.20.2 or 4.22.0, which contain the fix.
The fix introduces a new global configuration flag, js.interpretation.enabled, allowing administrators to control the interpretation of JavaScript expressions in these APIs, thereby mitigating the code injection risk.
| Product | Versions | Fixed in |
|---|---|---|
| apache/cloudstack | ≥ 4.18.0.0, < 4.20.2.0 | 4.20.2.0 |
| apache/cloudstack | all versions | — |
