CVE-2025-8963
📋 TL;DR
A remote deserialization vulnerability exists in jeecgboot JimuReport up to version 2.1.1, specifically in the Data Large Screen Template component's /drag/onlDragDataSource/testConnection endpoint. This allows attackers to execute arbitrary code on affected systems by sending specially crafted requests. Organizations using JimuReport versions up to 2.1.1 are vulnerable.
💻 Affected Systems
- jeecgboot JimuReport
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete system compromise, data theft, and lateral movement within the network.
Likely Case
Remote code execution allowing attackers to deploy malware, establish persistence, and exfiltrate sensitive data.
If Mitigated
Limited impact if network segmentation and proper access controls prevent exploitation attempts.
🎯 Exploit Status
While no public exploit exists, deserialization vulnerabilities are frequently weaponized. The vendor has confirmed the issue and provided a fix.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Version after 2.1.1 (specific version not specified in references)
Vendor Advisory: https://github.com/jeecgboot/jimureport/issues/4010
Restart Required: No
Instructions:
1. Upgrade JimuReport to version after 2.1.1. 2. Verify the /drag/onlDragDataSource/testConnection endpoint is no longer vulnerable. 3. Test application functionality after upgrade.
🔧 Temporary Workarounds
Block vulnerable endpoint
allRestrict access to the vulnerable /drag/onlDragDataSource/testConnection endpoint using web application firewall or network controls.
WAF rule: Block requests to */drag/onlDragDataSource/testConnection*
nginx/apache config: location ~ ^/drag/onlDragDataSource/testConnection { deny all; }
🧯 If You Can't Patch
- Implement strict network segmentation to isolate JimuReport instances from critical systems
- Deploy web application firewall with rules to detect and block deserialization attack patterns
🔍 How to Verify
Check if Vulnerable:
Check if JimuReport version is 2.1.1 or earlier and if the /drag/onlDragDataSource/testConnection endpoint is accessible.Check Version:
Check application configuration files or admin interface for version informationVerify Fix Applied:
After upgrade, verify the version is above 2.1.1 and test that the vulnerable endpoint no longer accepts malicious deserialization payloads.📡 Detection & Monitoring
