CVE-2017-15089
HIGHCVE-2017-15089 is a high-severity (CVSS 8.8) Deserialization of Untrusted Data vulnerability in org.infinispan:infinispan-core. O3 Security confirms whether CVE-2017-15089 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Deserialization of Untrusted Data in Infinispan
Blast Radius
org.infinispan:infinispan-coreReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.
Description
It was found that the Hotrod client in Infinispan before 9.2.0.CR1 would unsafely read deserialized data on information from the cache. An authenticated attacker could inject a malicious object into the data cache and attain deserialization on the client, and possibly conduct further attacks.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| ☕Maven | org.infinispan:infinispan-core | all versions | 9.2.0.CR1 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.infinispan:infinispan-core. 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.
Fix
Update org.infinispan:infinispan-core to 9.2.0.CR1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2017-15089 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 pinpoints whether CVE-2017-15089 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to CVE-2017-15089. 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-2017-15089 in your dependencies?
O3 detects CVE-2017-15089 across Maven dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
