Apache SeaTunnel, the widely used distributed data integration<\/a> platform, has disclosed a significant security vulnerability that enables unauthorized users to execute arbitrary file read operations and deserialization attacks through its RESTful API interface.\u00a0<\/p>\n The vulnerability, tracked as CVE-2025-32896 and reported on April 12, 2025, affects multiple versions of the platform and has been classified with moderate severity.<\/p>\n The security flaw impacts Apache SeaTunnel versions 2.3.1 through 2.3.10, creating a substantial exposure window for organizations utilizing these versions in production environments.\u00a0<\/p>\n The vulnerability stems from insufficient access controls in the platform\u2019s RESTful API-v1 implementation, specifically targeting the \/hazelcast\/rest\/maps\/submit-job endpoint.\u00a0<\/p>\n This endpoint, designed for job submission functionality, lacks proper authentication mechanisms, allowing malicious actors to exploit the system without valid credentials.<\/p>\n Security researcher Owen Amadeus discovered and reported this vulnerability, highlighting how unauthorized users can bypass security controls to access sensitive system resources.\u00a0<\/p>\n The technical nature of this flaw involves the manipulation of MySQL connection<\/a> parameters, where attackers can inject malicious payloads through URL parameters to achieve their objectives.\u00a0<\/p>\n This attack vector is particularly concerning because it combines two critical security risks: arbitrary file access and deserialization vulnerabilities, which can lead to remote code execution scenarios.<\/p>\n The exploitation mechanism centers around the manipulation of database connection strings within the SeaTunnel job submission process.\u00a0<\/p>\n Attackers can craft specially designed MySQL URLs containing additional parameters that trigger both arbitrary file read operations and Java deserialization attacks. The vulnerable endpoint \/hazelcast\/rest\/maps\/submit-job processes these malicious requests without proper validation or authentication checks.<\/p>\n The deserialization component of this attack is particularly dangerous, as it can allow attackers to execute arbitrary code on the target system.<\/p>\n By submitting crafted serialized objects through the job submission interface, malicious actors can potentially gain complete control over the affected SeaTunnel instance.\u00a0<\/p>\n This type of vulnerability exploits Java\u2019s object serialization mechanism, where untrusted data can be deserialized into executable code, bypassing traditional security boundaries.<\/p>\nApache SeaTunnel RCE Vulnerability<\/strong><\/h2>\n
