Apache Kylin: Insufficiently Protected Credentials
CVE-2023-29055 is a high-severity insufficiently protected credentials vulnerability in Apache Kylin from Apache, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected Apache Kylin versions: 2.0.0 through 4.0.3. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 1.15% chance of exploitation within 30 days, higher than 67% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Kylin to 4.0.4 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official 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.

The underlying weakness: Insufficiently Protected Credentials
The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval.
How developers prevent this class of flaw
- Use an appropriate security mechanism to protect the credentials.
- Make appropriate use of cryptography to protect the credentials.
- Use industry standards to protect the credentials (e.g. LDAP, keystore, etc.).
