Overview
This blog post will delve into the CVE-2025-49002 vulnerability, a critical flaw found in DataEase, an open-source business intelligence and data visualization tool. This vulnerability specifically impacts versions of DataEase prior to version 2.10.10 and allows the patch for CVE-2025-32966 to be bypassed through case insensitivity. As a result, potential system compromise or data leakage can occur, posing a significant threat to businesses relying on this software for their data management needs.

How the Exploit Works
The exploit works by bypassing the patch for the previous vulnerability, CVE-2025-32966. Due to case insensitivity, commands like INIT and RUNSCRIPT, which are typically prohibited, can still be executed. This opens the door for an attacker to manipulate the system and potentially gain unauthorized access or leak sensitive data.
Conceptual Example Code
An example of how the vulnerability might be exploited could involve a malicious actor sending a specially crafted request, like this:
POST /DataEase/RunScript HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "command": "init" }In this hypothetical scenario, the actor sends a POST request to the RunScript endpoint. The command “init”, which is typically prohibited, is included in the request body. Due to the case insensitivity issue, the command could be executed, bypassing the intended security measures.
Mitigation Guidance
The official recommendation to mitigate this vulnerability is to apply the vendor patch by upgrading to DataEase v2.10.10. If immediate patching is not possible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) may serve as temporary mitigation until the vendor patch can be applied. However, as no known workarounds are available, updating to the fixed version is the most effective way to secure systems against this vulnerability.
