CVE-2018-1295: Possible Execution of Arbitrary Code Within Deserialization
Endpoints of Apache Ignite

Severity: Important

Vendor: The Apache Software Foundation

Versions Affected: Apache Ignite 2.3 or earlier

Impact:
An attacker can execute arbitrary code on Ignite nodes in the case when
Ignite classpath contains arbitrary vulnerable classes.

Description:
Apache Ignite 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.

Mitigation:
•    All Ignite versions: make sure there are no vulnerable classes among
your custom code used in Apache Ignite.
•    Ignite 2.3 or earlier users: upgrade to Ignite 2.4 and use
IGNITE_MARSHALLER_WHITELIST and/or IGNITE_MARSHALLER_BLACKLIST system
properties to define classes allowed for deserialization

The vulnerability was discovered by Man Yue Mo of lgtm.com.
