CVE-2018-1295
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIn Apache Ignite 2.3 or earlier, the serialization mechanism does not have a list of classes allowed for serialization/deserialization, which makes it possible to run arbitrary code when 3-rd party vulnerable classes are present in Ignite classpath. The vulnerability can be exploited if the one sends a specially prepared form of a serialized object to one of the deserialization endpoints of some Ignite components - discovery SPI, Ignite persistence, Memcached endpoint, socket steamer.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceIn Apache Ignite 2.3 and earlier, the serialization mechanism lacks a whitelist of allowed classes, enabling remote code execution via malicious serialized objects sent to deserialization endpoints (discovery SPI, Ignite persistence, Memcached, socket streamer).

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Apache Ignite versionLocate the ignite-core JAR file in your deployment and check its version number, or run: java -cp ignite-core-*.jar org.apache.ignite.Ignition 2>&1 | grep -i versionAffected if The installed version is 2.3.0 or earlier
-
Verify deserialization endpoints are exposedReview your Ignite configuration (XML files or programmatic config) for enabled SPI implementations: DiscoverySpi, Memcached communication, or socket streaming. Check for open network listeners on ports used by these services (typically 47100 for discovery, 11211 for Memcached, or custom streamer ports)Affected if Any of these SPI endpoints are enabled and accessible on the network
-
Confirm Ignite persistence is in useExamine your Ignite configuration for DataStorageConfiguration with persistence enabled, or check for 'setPersistenceEnabled(true)' in programmatic configAffected if Ignite native persistence is enabled and storing data to disk
-
Check for deserialization consumer configurationsInspect your ignite.xml or configuration beans for 'TcpDiscoverySpi', 'TcpCommunicationSpi', or custom serializer settings that handle incoming serialized objectsAffected if Any SPI or component is configured to accept and deserialize objects from untrusted sources
You are affected if Apache Ignite version is 2.3.0 or earlier AND any deserialization endpoint (discovery SPI, Memcached, socket streamer) or Ignite persistence is enabled and accessible on the network.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade to Apache Ignite 2.4 or later which implements class whitelisting for serialization; if immediate upgrade is not feasible, restrict network access to Ignite deserialization endpoints and audit the classpath for vulnerable serializable classes.
Apache Ignite 2.4.0 or later
- Download Apache Ignite 2.4.0 or later from the official Apache Ignite releases repository
- Stop all Ignite nodes and services that use the affected version
- Backup your existing Ignite configuration files and any persisted data
- Install the new Ignite 2.4.0+ binaries on all nodes
- Review and update Ignite configuration to ensure compatibility with 2.4.0+ (check XML configs, Spring beans, and programmatic configurations)
- Test the upgrade in a staging environment before deploying to production
- Deploy the upgraded Ignite nodes and restart services
- Verify that all deserialization endpoints (discovery SPI, persistence, Memcached, socket streamer) are functioning correctly
