CVE-2022-43183: n/a in n/a
XXL-Job before v2.3.1 contains a Server-Side Request Forgery (SSRF) via the component /admin/controller/JobLogController.java.
AI Analysis
Technical Summary
CVE-2022-43183 is a high-severity Server-Side Request Forgery (SSRF) vulnerability identified in the XXL-Job scheduling platform prior to version 2.3.1. The vulnerability resides specifically in the /admin/controller/JobLogController.java component. SSRF vulnerabilities allow an attacker to induce the server-side application to make HTTP requests to arbitrary domains or IP addresses, potentially bypassing firewall rules and accessing internal resources that are otherwise inaccessible externally. In this case, the vulnerability allows an attacker with at least low privileges (PR:L) to send crafted requests without requiring user interaction (UI:N), exploiting the flaw remotely over the network (AV:N) with low attack complexity (AC:L). The impact is significant, as indicated by the CVSS 3.1 score of 8.8, reflecting high confidentiality, integrity, and availability impacts (C:H/I:H/A:H). This means an attacker could exfiltrate sensitive data, manipulate or delete data, and disrupt service availability. The vulnerability scope is unchanged (S:U), meaning the exploit affects the vulnerable component and its privileges without extending beyond the original security scope. Although no known exploits are currently reported in the wild, the presence of this SSRF in a job scheduling system that typically interacts with internal services and databases makes it a critical risk. XXL-Job is an open-source distributed task scheduling framework widely used in enterprise environments to automate and manage scheduled jobs, often integrated with internal APIs and backend services. The lack of vendor or product-specific details limits precise identification, but the vulnerability's nature and affected component suggest that any deployment of XXL-Job prior to v2.3.1 is at risk if exposed to untrusted users with some level of access to the admin interface.
Potential Impact
For European organizations, the impact of CVE-2022-43183 can be severe, especially for enterprises relying on XXL-Job for critical business process automation. The SSRF vulnerability could allow attackers to pivot from the scheduling platform into internal networks, accessing sensitive internal APIs, databases, or cloud metadata services. This could lead to data breaches involving personal data protected under GDPR, intellectual property theft, or disruption of automated workflows critical to business operations. Given the high confidentiality, integrity, and availability impacts, organizations could face operational downtime, regulatory fines, and reputational damage. Sectors such as finance, healthcare, manufacturing, and public administration, which often use job scheduling for batch processing and system orchestration, are particularly vulnerable. The vulnerability's exploitation could also facilitate lateral movement within networks, increasing the risk of broader compromise. Since the vulnerability requires at least low privileges, insider threats or compromised user accounts could be leveraged to exploit this flaw. The absence of known exploits in the wild does not reduce the urgency, as the vulnerability has been public since November 2022, providing ample time for attackers to develop exploits.
Mitigation Recommendations
1. Immediate upgrade to XXL-Job version 2.3.1 or later, where the SSRF vulnerability has been addressed, is the most effective mitigation. 2. Restrict access to the XXL-Job admin interface to trusted internal networks and authenticated users only, employing network segmentation and strong access controls. 3. Implement strict input validation and output encoding on any user-supplied data that interacts with internal HTTP requests, to prevent SSRF payloads. 4. Deploy Web Application Firewalls (WAFs) with custom rules to detect and block suspicious outbound requests originating from the XXL-Job server, especially those targeting internal IP ranges or cloud metadata endpoints. 5. Monitor logs for unusual outbound HTTP requests from the XXL-Job server, focusing on requests to internal services or unexpected external domains. 6. Conduct regular security audits and penetration testing on the scheduling platform and its integrations to identify and remediate similar vulnerabilities. 7. Employ the principle of least privilege for user accounts accessing XXL-Job, ensuring that only necessary permissions are granted to reduce exploitation risk. 8. If patching is delayed, consider temporary network-level controls such as egress filtering to block unauthorized outbound requests from the XXL-Job server.
