CVE-2018-1295: Apache Ignite

Critical severity, CVSS 9.8. EPSS: 6.3% chance of exploitation in the next 30 days.

In 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.

Affected products

• Apache Ignite: up to and including 2.3.0
