CVE-2017-15693 : Security Advisory and Response

Apache Geode before version 1.4.0 is susceptible to remote code execution due to unsafe deserialization of application objects.

Understanding CVE-2017-15693

Apache Geode, an in-memory data grid, is affected by improper input validation leading to potential remote code execution.

What is CVE-2017-15693?

Prior to version 1.4.0, Apache Geode stores application objects in serialized form. Deserialization during specific cluster operations and API calls can allow an attacker with DATA:WRITE privileges to execute remote code if specific classes are available on the classpath.

The Impact of CVE-2017-15693

The vulnerability could be exploited by an attacker with DATA:WRITE access to the cluster, potentially leading to remote code execution.

Technical Details of CVE-2017-15693

Apache Geode's vulnerability involves unsafe deserialization of application objects, posing a risk of remote code execution.

Vulnerability Description

Apache Geode retains application objects in a serialized format within its server
Deserialization of these objects may occur during specific cluster operations and API calls
An individual with DATA:WRITE privileges could potentially initiate remote code execution if specific classes are accessible on the classpath

Affected Systems and Versions

Product: Apache Geode
Vendor: Apache Software Foundation
Versions Affected: 1.0.0 to 1.3.0

Exploitation Mechanism

Attacker with DATA:WRITE privileges exploits deserialization of application objects to execute remote code

Mitigation and Prevention

Immediate Steps to Take:

Upgrade Apache Geode to version 1.4.0 or later
Restrict access to the cluster to authorized users only
Monitor and review classpath for unauthorized classes Long-Term Security Practices:
Implement secure coding practices to prevent deserialization vulnerabilities
Regularly update and patch Apache Geode to mitigate known security risks
