CVE-2018-8018: Apache Ignite

Critical severity, CVSS 9.8. EPSS: 6.7% chance of exploitation in the next 30 days.

In Apache Ignite before 2.4.8 and 2.5.x before 2.5.3, 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 GridClientJdkMarshaller deserialization endpoint.

Affected products

• Apache Ignite: before 2.4.8 (fixed in 2.4.8); after 2.5.0, before 2.5.3 (fixed in 2.5.3)
