Apache Kylin has Insufficiently Protected Credentials

High severity GitHub Reviewed Published Jan 29, 2024 to the GitHub Advisory Database • Updated Feb 2, 2024

Package

maven org.apache.kylin:kylin-core-common (Maven)

Affected versions

>= 2.0.0, < 4.0.4

Patched versions

4.0.4

Description

In Apache Kylin version 2.0.0 to 4.0.3, there is a Server Config web interface that displays the content of file 'kylin.properties', that may contain serverside credentials. When the kylin service runs over HTTP (or other plain text protocol), it is possible for network sniffers to hijack the HTTP payload and get access to the content of kylin.properties and potentially the containing credentials.

To avoid this threat, users are recommended to 

  • Always turn on HTTPS so that network payload is encrypted.

  • Avoid putting credentials in kylin.properties, or at least not in plain text.

  • Use network firewalls to protect the serverside such that it is not accessible to external attackers.

  • Upgrade to version Apache Kylin 4.0.4, which filters out the sensitive content that goes to the Server Config web interface.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
