Overview<\/strong><\/p>\n

The Common Vulnerabilities and Exposures (CVE) system has recently identified a severe vulnerability, known as CVE-2025-49001, in DataEase, an open-source business intelligence and data visualization tool. This vulnerability, due to ineffective secret verification, allows users to forge a JSON Web Token (JWT), potentially leading to unauthorized access or malicious activities. This flaw can impact any organization or individual using versions of DataEase prior<\/a> to v2.10.10.
\nThe severity of this vulnerability<\/a> is underscored by its CVSS score of 9.8, indicating a critical threat. The potential for system compromise and data leakage makes it crucial for users to understand this vulnerability and take necessary steps to mitigate its impact<\/a>.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-49001
\nSeverity: Critical (CVSS:9.8)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Potential system compromise or data leakage<\/a><\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

DataEase | Prior to v2.10.10<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The exploit takes advantage of a flaw in the secret verification process of DataEase. In versions prior<\/a> to 2.10.10, the verification process doesn’t work effectively, allowing an attacker to use any secret to forge a JWT token. This token can then be used to gain unauthorized access<\/a> to the system, potentially compromising sensitive data or disrupting system operations.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Here’s a conceptual example of how the vulnerability might be exploited:<\/p>\n

POST \/token HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{\n\"algorithm\": \"HS256\",\n\"typ\": \"JWT\",\n\"kid\": \"anySecret\",\n\"payload\": {\n\"user\": \"admin\"\n},\n\"signature\": \"...\"\n}<\/code><\/pre>\n
In this example, an attacker sends a POST request<\/a> to the \/token URI with a forged JWT. The system, due to its flawed secret verification process, accepts the ‘anySecret’ value in the ‘kid’ field, and the attacker gains unauthorized access<\/a> as an admin user.<\/p>\n
Mitigation Recommendations<\/strong><\/p>\n
Users are strongly advised to update DataEase to version 2.10.10 or later, where the vulnerability has been fixed. If an immediate update is not possible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation. However, these measures only offer temporary protection and cannot completely resolve the vulnerability<\/a>. Therefore, updating to a patched version remains the most effective solution.<\/p>\n","protected":false},"excerpt":{"rendered":"
