CVSSv3.1 Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N

Bug ID: SPL-173641, SPL-129677

Security Content: Splunk protocol impersonation weak encryption simplerequest 

Description

The httplib and urllib Python libraries that Splunk shipped with Splunk Enterprise did not validate certificates using the certificate authority (CA) certificate stores by default in Splunk Enterprise versions before 9.0 and Splunk Cloud Platform versions before 8.2.2203. Python 3 client libraries now verify server certificates by default and use the appropriate CA certificate stores for each library. Apps and add-ons that include their own HTTP libraries are not affected.

For Splunk Enterprise, upgrade to version 9.0 or higher and Configure TLS host name validation for Splunk Python modules to enable the remediation.

At the time of publishing, we have no evidence of exploitation of this vulnerability by external parties.

 

Solution

For Splunk Enterprise, upgrade to version 9.0 or higher and Configure TLS host name validation for Splunk Python modules.

For Splunk Cloud Platform customers, Splunk is actively patching and monitoring Splunk Cloud instances.
