Overview
In this blog post, we will delve into a crucial vulnerability that affects DataEase, a widely used open-source business intelligence and data visualization tool. Designated CVE-2025-48999, this vulnerability is a bypass of a previous patch, CVE-2025-46566, and exists in versions of DataEase prior to 2.10.10. The issue at hand is of serious concern as its exploitation could potentially lead to system compromise or data leakage, jeopardizing both system integrity and user privacy.
Vulnerability Summary
CVE ID: CVE-2025-48999
Severity: Critical, CVSS score 8.8
Attack Vector: Network
Privileges Required: Low
User Interaction: None
Impact: Potential system compromise or data leakage
Affected Products
Product | Affected Versions
DataEase | Versions prior to 2.10.10
How the Exploit Works
The exploit takes advantage of the `getUrlType()` function in DataEase, which retrieves the `hostname`. The judgement statement in the function returns false, causing the function not to enter the if statement and subsequently not be filtered. Because of this, a threat actor can construct a malicious JDBC statement by directly concatenating the payload at the replace location.
Conceptual Example Code
A conceptual example of the exploitation of this vulnerability might look like this:
String hostName = getUrlType();
String maliciousPayload = "'; DROP TABLE users;--";
String jdbcStatement = "jdbc:DataEase:" + hostName + maliciousPayload;
// The jdbcStatement now contains a SQL injection
executeQuery(jdbcStatement);The above example depicts a basic SQL injection attack, where a malicious payload is concatenated with the hostname. This turns into a JDBC statement that, when executed, could potentially lead to harmful consequences, such as data deletion or system compromise.
Mitigation Guidance
The recommended course of action is to update DataEase to version 2.10.10 or later, which contains a patch for this issue. If an immediate update is not viable, implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. Nevertheless, these should only be viewed as temporary measures until the software can be updated to a secure version. Always ensure to follow vendor-specific guidelines for patching and updates.
This vulnerability underscores the importance of timely patching and updating software. By keeping systems up to date, organizations can help protect themselves from potential cyber threats.
