Which packages are affected by CVE-2024-45384?

CVE-2024-45384 affects the following packages: org.apache.druid.extensions:druid-pac4j (Maven). Ecosystems affected: Maven.

How do I fix CVE-2024-45384?

Update org.apache.druid.extensions:druid-pac4j to 30.0.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-45384 is resolved across your whole dependency graph.

How do I detect CVE-2024-45384 in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.druid.extensions:druid-pac4j. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate CVE-2024-45384 if there is no patch (or I can't update yet)?

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 does O3 Security protect against CVE-2024-45384?

O3 pinpoints whether CVE-2024-45384 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2024-45384 actively exploited in the wild?

No public exploit code has been indexed for CVE-2024-45384 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2024-45384?

CVE-2024-45384 has an EPSS (Exploit Prediction Scoring System) score of 0.8%, placing it in the 52th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2024-45384?

Description

Padding Oracle vulnerability in Apache Druid extension, druid-pac4j. This could allow an attacker to manipulate a pac4j session cookie.

This issue affects Apache Druid versions 0.18.0 through 30.0.0. Since the druid-pac4j extension is optional and disabled by default, Druid installations not using the druid-pac4j extension are not affected by this vulnerability.

While we are not aware of a way to meaningfully exploit this flaw, we nevertheless recommend upgrading to version 30.0.1 or higher which fixes the issue and ensuring you have a strong druid.auth.pac4j.cookiePassphrase as a precaution.
