Hi, I'm Sharon, a product manager at Chaitin Tech. We build SafeLine, an open-source Web Application Firewall built for real-world threats. While SafeLine focuses on HTTP-layer protection, our emergency response center monitors and responds to RCE and authentication vulnerabilities across the stack to help developers stay safe.
Smartbi is a widely used enterprise Business Intelligence (BI) platform that provides data visualization, multi-source integration, and reporting features. It’s designed to help organizations analyze data efficiently and make smarter, data-driven decisions.
On July 31, 2025, Smartbi released a security patch fixing a Remote Code Execution (RCE) vulnerability. This flaw allows attackers to bypass authentication and trigger dangerous backend methods, ultimately achieving remote command execution on the affected server.
The exploit difficulty is low, and the potential impact is critical — making this a high-priority patch for all Smartbi users.
Vulnerability Overview
Root Cause
The authentication mechanism in Smartbi contains a design flaw. Attackers can leverage a default resource ID to bypass session validation and obtain valid session tokens. With this, they can invoke backend APIs to reflectively call dangerous methods, resulting in remote code execution.
Impact
- Full server takeover
- Data exfiltration
- Compromise of business-critical systems
