Overview
CVE-2025-48998 is a severe cybersecurity vulnerability affecting DataEase, an open-source business intelligence and data visualization tool. This vulnerability exposes systems to potential compromise and data leakage, presenting a significant risk to system integrity and user data confidentiality. Users and administrators of DataEase should be aware of this vulnerability, as it could potentially allow malicious actors to read and deserialize arbitrary files through the background JDBC connection. This level of exposure could lead to unauthorized access to sensitive data, compromising system control, and a high potential for exploitation.

How the Exploit Works
The exploit takes advantage of the vulnerability in the patch for CVE-2025-27103, bypassing it to allow authenticated users to read and deserialize arbitrary files through the background JDBC connection. This allows for the possibility of a malicious actor gaining access to sensitive data stored within these files, making this vulnerability particularly dangerous.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited, represented through a shell command:
# The attacker would need to be authenticated first
$ curl -u username:password http://target.example.com/login
# Once authenticated, the attacker could send a malicious request to the JDBC endpoint
$ curl -X POST -H "Content-Type: application/json" -d '{"filePath": "/etc/passwd"}' http://target.example.com/jdbc/readIn this example, the attacker sends a POST request to the JDBC endpoint specifying a path to a file in the data payload. This could potentially allow the attacker to read arbitrary files on the affected system.
Mitigation Guidance
The most effective way to protect your system from this vulnerability is to apply the vendor patch. DataEase has fixed this vulnerability in version 2.10.10. Updating to this or a more recent version is advised. If you are unable to update immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) could serve as temporary mitigation. However, these should not be seen as a long-term solution. Regular updates and patching are essential to maintaining a secure system.
