CVSS v3.1

Official Description

Apache Geode versions up to 1.12.5, 1.13.4 and 1.14.0 are vulnerable to a deserialization of untrusted data flaw when using JMX over RMI on Java 8. Any user still on Java 8 who wishes to protect against deserialization attacks involving JMX or RMI should upgrade to Apache Geode 1.15 and Java 11. If upgrading to Java 11 is not possible, then upgrade to Apache Geode 1.15 and specify "--J=-Dgeode.enableGlobalSerialFilter=true" when starting any Locators or Servers. Follow the documentation for details on specifying any user classes that may be serialized/deserialized with the "serializable-object-filter" configuration option. Using a global serial filter will impact performance.

Risk Analysis

Apache Geode is vulnerable to deserialization of untrusted data when using JMX over RMI on Java 8. This critical flaw allows remote attackers to execute arbitrary code, necessitating an upgrade to Java 11 or specific configuration changes.

No public exploit is known, and it is not in KEV. The vulnerability is remotely exploitable.

Recommended Action

Upgrade to Apache Geode 1.15 and Java 11, or apply the recommended global serial filter configuration if Java 11 is not feasible.

Technical Analysis

CVE-2022-37021 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.

From a weakness classification perspective (CWE-502): Insecure deserialization vulnerabilities allow attackers to inject malicious objects during deserialization, potentially enabling remote code execution.
