Apache Hadoop is an open-source software framework used for distributed storage and processing of big data sets using the MapReduce programming model.

CVE-2017-3161: ebHDFS client might send SPNEGO authorization header to remote URL without proper verification. A crafty user can trigger services to send server credentials to a webhdfs path for capturing the service principal.

Affected Versions:
Apache Hadoop 3.2.0 to 3.2.1, 3.0.0-alpha1 to 3.1.3, 2.0.0-alpha to 2.10.0

QID Detection Logic:
This QID matches the versions of vulnerable Apache Hadoop installations by launching a Hadoop version request.

Successful exploitation could allows privilege escalation.

CVSS V3 rated as Critical - 8.8 severity.

CVSS V2 rated as High - 6.5 severity.

Solution

Customers are advised to upgrade to Apache Hadoop 3.3.0, 3.2.2, 3.1.4, 2.10.1 or later versions to remediate these vulnerabilities.

Workaround:
Set different http signature secrets and use dedicated hosts for each privileged impersonation service (such as HiveServer2).
