CVE-2025-59302: Apache CloudStack: Potential remote code execution on Javascript engine defined rules

[Harikrishna Patnala <harikrishna () apache org>]

Severity: low 

Affected versions:

- Apache CloudStack 4.18.0 before 4.20.2
- Apache CloudStack 4.21.0 before 4.22.0

Description:

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.
