CVE-2018-1295 : What You Need to Know

Apache Ignite versions 2.3 and earlier are vulnerable to a security risk due to the lack of a predefined list of permitted classes for serialization and deserialization. This can lead to the execution of malicious code through specially crafted serialized objects.

Understanding CVE-2018-1295

Apache Ignite's vulnerability allows for potential execution of arbitrary code through deserialization endpoints, posing a risk of information disclosure.

What is CVE-2018-1295?

In Apache Ignite versions 2.3 and prior, the absence of a designated list of classes for serialization and deserialization can enable the execution of malicious code if vulnerable third-party classes are present in the Ignite classpath. Attackers can exploit this by sending manipulated serialized objects to various deserialization endpoints in Ignite components.

The Impact of CVE-2018-1295

The vulnerability in Apache Ignite can result in the execution of arbitrary code, potentially leading to information disclosure.

Technical Details of CVE-2018-1295

Apache Ignite's vulnerability stems from inadequate class validation for serialization and deserialization processes.

Vulnerability Description
