CVE-2025-32896: CWE-306 Missing Authentication for Critical Function in Apache Software Foundation Apache SeaTunnel
# Summary Unauthorized users can perform Arbitrary File Read and Deserialization attack by submit job using restful api-v1. # Details Unauthorized users can access `/hazelcast/rest/maps/submit-job` to submit job. An attacker can set extra params in mysql url to perform Arbitrary File Read and Deserialization attack. This issue affects Apache SeaTunnel: <=2.3.10 # Fixed Users are recommended to upgrade to version 2.3.11, and enable restful api-v2 & open https two-way authentication , which fixes the issue.
AI Analysis
Technical Summary
CVE-2025-32896 is a critical vulnerability identified in Apache SeaTunnel versions up to and including 2.3.10, a data integration and processing platform developed by the Apache Software Foundation. The vulnerability stems from CWE-306, which indicates missing authentication for a critical function. Specifically, unauthorized users can access the RESTful API endpoint `/hazelcast/rest/maps/submit-job` without any authentication controls. This endpoint allows job submissions, and due to the lack of authentication, attackers can submit malicious jobs. By manipulating parameters within the MySQL connection URL, attackers can exploit this flaw to perform arbitrary file read operations and deserialization attacks. Arbitrary file read can lead to exposure of sensitive files on the server, including configuration files, credentials, or other critical data. Deserialization attacks can enable remote code execution or other malicious behaviors by injecting crafted serialized objects that the system deserializes insecurely. The vulnerability is particularly severe because it does not require any authentication or user interaction, making it trivially exploitable by remote attackers with network access to the API endpoint. The issue was addressed in Apache SeaTunnel version 2.3.11 by enforcing authentication through the adoption of RESTful API v2 and enabling HTTPS two-way authentication, which ensures both client and server verify each other's identities, mitigating unauthorized access. No known exploits are currently reported in the wild, but the potential impact and ease of exploitation make this a high-risk vulnerability for affected deployments.
Potential Impact
For European organizations using Apache SeaTunnel, especially those relying on versions 2.3.10 or earlier, this vulnerability poses a significant risk. The arbitrary file read capability can lead to exposure of sensitive corporate data, including database credentials, internal configuration files, or personally identifiable information (PII), potentially violating GDPR and other data protection regulations. Deserialization attacks could allow attackers to execute arbitrary code on the affected servers, leading to full system compromise, lateral movement within networks, and disruption of critical data processing workflows. This could impact sectors such as finance, telecommunications, manufacturing, and public services that utilize Apache SeaTunnel for data integration and analytics. The lack of authentication means that any exposed API endpoint is vulnerable to remote exploitation, increasing the attack surface. Additionally, the breach of confidentiality and integrity of data processed by SeaTunnel could undermine trust and lead to regulatory penalties. The availability of services may also be affected if attackers leverage this vulnerability to disrupt or manipulate data pipelines. Given the increasing reliance on data-driven decision-making in European enterprises, the operational and reputational impact could be substantial.
Mitigation Recommendations
To mitigate this vulnerability, European organizations should immediately upgrade Apache SeaTunnel to version 2.3.11 or later, where the issue is fixed. Beyond upgrading, organizations should: 1) Disable or restrict access to the vulnerable RESTful API v1 endpoints, especially `/hazelcast/rest/maps/submit-job`, until the upgrade is applied. 2) Enforce network-level access controls such as firewall rules or VPNs to limit API access to trusted internal networks or authenticated users only. 3) Enable and configure RESTful API v2 with HTTPS two-way authentication as recommended by the vendor to ensure mutual authentication between clients and servers. 4) Conduct thorough audits of existing SeaTunnel deployments to identify any unauthorized job submissions or suspicious activity that may indicate exploitation attempts. 5) Implement runtime application self-protection (RASP) or web application firewalls (WAF) with custom rules to detect and block anomalous API requests targeting job submission endpoints. 6) Regularly monitor logs and alerts for unusual deserialization patterns or file access attempts. 7) Educate DevOps and security teams about secure configuration and the importance of applying vendor patches promptly. These steps go beyond generic patching advice by emphasizing access control, monitoring, and secure API usage.
