Apache · Apache Kylin · CVE-2023-29055
**Name of the Vulnerable Software and Affected Versions**
Apache Kylin versions 2.0.0 through 4.0.3
**Description**
The issue concerns the Server Config web interface in Apache Kylin, which displays the content of the `kylin.properties` file. This file may contain server-side credentials. When the Kylin service runs over HTTP or other plain text protocols, it is possible for network sniffers to hijack the HTTP payload and access the content of `kylin.properties`, potentially obtaining the contained credentials.
**Recommendations**
* For versions 2.0.0 through 4.0.3, always turn on HTTPS to encrypt the network payload.
* For versions 2.0.0 through 4.0.3, avoid putting credentials in `kylin.properties`, or at least not in plain text.
* For versions 2.0.0 through 4.0.3, use network firewalls to protect the server-side, making it inaccessible to external attackers.
* Upgrade to version Apache Kylin 4.0.4, which filters out sensitive content that goes to the Server Config web interface.
