DescriptionNVD

Deserialization of Untrusted Data vulnerability in Apache Camel LevelDB component.

The Camel-LevelDB DefaultLevelDBSerializer class deserializes data read from the LevelDB aggregation repository using java.io.ObjectInputStream without applying any ObjectInputFilter or class-loading restrictions. An attacker who can write to the LevelDB database files used by a Camel application can inject a crafted serialized Java object that, when deserialized during normal aggregation repository operations, results in arbitrary code execution in the context of the application. This issue affects Apache Camel: from 4.10.0 before 4.10.8, from 4.14.0 before 4.14.5, from 4.15.0 before 4.18.0.

Users are recommended to upgrade to version 4.18.0, which fixes the issue. For the 4.10.x LTS releases, users are recommended to upgrade to 4.10.9, while for 4.14.x LTS releases, users are recommended to upgrade to 4.14.5

Executive ViewAI

Why It Matters

A critical deserialization vulnerability in Apache Camel's LevelDB component could allow attackers to execute arbitrary code on systems using this component, potentially compromising data integrity and system availability. Organizations running Apache Camel with LevelDB aggregation repositories are at immediate risk, particularly in production environments handling sensitive data or critical operations.

Business Impact: High

Compensating Controls

Disable the LevelDB aggregation repository component if not critical to operations; implement network segmentation to restrict access to Camel services to trusted networks only; deploy WAF rules to block suspicious serialized Java object payloads; monitor for unusual deserialization activity in application logs; restrict file system permissions on LevelDB data directories; apply strict input validation and rate limiting on data sources feeding into Camel aggregation; consider running Camel instances in isolated containers with minimal privileges and restricted outbound connections.

Attack Technique

Insecure Deserialization CRITICAL

Insecure deserialization occurs when an application converts serialized data (a stream of bytes representing an object's state) back into a living object without proper validation.

Remote Code Execution CRITICAL

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
