Apache Kylin: Insufficiently protected credentials in config file
Exploitation Status
No confirmed exploitation observed yet
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- CISA’s own triage has not observed active exploitation or public proof-of-concept code for this CVE as of its last assessment.
Exploitation and automatability from CISA’s SSVC triage for CVE-2023-29055.
EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
CVE-2023-29055 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 377,166 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.
Real-World Exposure

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.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.kylin:kylin-core-common, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update org.apache.kylin:kylin-core-common to 4.0.4 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-29055 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2023-29055 can be triaged on real exposure rather than presence alone.
Tailored to CVE-2023-29055. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2023-29055 in your dependencies?
O3 Security finds CVE-2023-29055 across Maven dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
