CVE-2017-9794
MEDIUMCVE-2017-9794 is a medium-severity (CVSS 4.3) Information Exposure vulnerability in org.apache.geode:geode-core. O3 Security confirms whether CVE-2017-9794 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Apache Geode gfsh query vulnerability
Blast Radius
org.apache.geode:geode-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
When a cluster is operating in secure mode, a user with read privileges for specific data regions can use the gfsh command line utility to execute queries. In Apache Geode before 1.2.1, the query results may contain data from another user's concurrently executing gfsh query, potentially revealing data that the user is not authorized to view.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| ☕Maven | org.apache.geode:geode-core | ≥ 1.0.0&&< 1.2.1 | 1.2.1 |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.geode:geode-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.apache.geode:geode-core to 1.2.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2017-9794 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-2017-9794 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-2017-9794. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
