Horizon Alert
Summary of the vulnerability and why it matters
This critical vulnerability in JimuReport allows remote code execution by processing specially crafted H2 JDBC URLs. This could enable attackers to run arbitrary Java code on affected systems without any user interaction, posing a significant security risk.
- Remote code execution via malicious URLs.
- Critical vulnerability impacts reporting tools.
- Confirm relevance and exposure of JimuReport.
Attack Path
How an attacker could exploit the issue
An attacker can remotely execute arbitrary Java code by submitting a specially crafted H2 JDBC URL to the JimuReport application. This occurs because the application directly uses user-supplied URLs with the H2 driver, bypassing security checks and allowing the execution of malicious directives.
- No authentication or user interaction required.
- Vulnerable component: H2 JDBC URL processing.
- Risk: Remote code execution.
Live Threat
Current exploitation, exposure, and threat context
When JimuReport processes user-controlled H2 JDBC URLs, it may allow for remote code execution. This could affect the application's service behavior and any sensitive information it can access when the application passes the attacker-supplied JDBC URL directly to the H2 driver and the necessary directives are used.
- Arbitrary Java code execution.
- Network access can exploit it.
- Compromise of the reporting service.
Operational Fix
Recommended remediation, mitigation, and detection steps
The application owner is responsible for JimuReport, a reporting and dashboarding tool that can be exposed as an internet-facing service. The initial step is to identify all instances of JimuReport, confirm their exposure and criticality, and then coordinate remediation with the platform or infrastructure team, and potentially the vendor management team if a vendor-supplied product.
- Confirm JimuReport instances and exposure.
- Identify accountable application owners.
- Plan remediation based on identified risk.
