CVE-2024-55953
📋 TL;DR
This vulnerability in DataEase allows authenticated users to read and deserialize arbitrary files through JDBC connection parameters. Attackers can exploit this to access sensitive system files or execute arbitrary code. All DataEase installations with versions below v1.18.27 are affected.
💻 Affected Systems
- DataEase
📦 What is this software?
Dataease by Dataease
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise through arbitrary file read leading to credential theft, followed by remote code execution via deserialization attacks.
Likely Case
Unauthorized access to sensitive files containing credentials, configuration data, or business information stored on the server.
If Mitigated
Limited impact if proper network segmentation and least privilege access controls are implemented, restricting authenticated user access.
🎯 Exploit Status
Exploitation requires authenticated access but is straightforward once credentials are obtained.
