Affected versions:
- Apache Druid before 31.0.2
- Apache Druid before 32.0.1
Description:
Severity: medium (5.8) / important
Server-Side Request Forgery (SSRF), Improper Neutralization of Input During Web
Page Generation ('Cross-site Scripting'), URL Redirection to Untrusted Site
('Open Redirect') vulnerability in Apache Druid.
This issue affects all previous Druid versions.
When using the Druid management proxy, a request that has a specially crafted
URL could be used to redirect the request to an arbitrary server instead. This
has the potential for XSS or XSRF. The user is required to be authenticated for
this exploit. The management proxy is enabled in Druid's out-of-box
configuration. It may be disabled to mitigate this vulnerability. If the
management proxy is disabled, some web console features will not work properly,
but core functionality is unaffected.
Users are recommended to upgrade to Druid 31.0.2 or Druid 32.0.1, which fixes
the issue.
