CVE-2025-10492
📋 TL;DR
A Java deserialization vulnerability in Jaspersoft Library allows remote attackers to execute arbitrary code by sending malicious serialized objects. This affects any system using the vulnerable library, potentially compromising entire applications and underlying servers. The high CVSS score indicates critical risk requiring immediate attention.
💻 Affected Systems
- Jaspersoft Library
- JasperReports
- Applications using vulnerable Jaspersoft components
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise leading to data theft, ransomware deployment, lateral movement across networks, and persistent backdoor installation.
Likely Case
Remote code execution allowing attackers to steal sensitive data, disrupt services, or use the system as a foothold for further attacks.
If Mitigated
Limited impact if proper network segmentation, input validation, and security controls prevent exploitation attempts.
🎯 Exploit Status
Java deserialization vulnerabilities are commonly exploited with publicly available tools and payloads
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not available
Vendor Advisory: https://community.jaspersoft.com/advisories/jaspersoft-security-advisory-september-16-2025-jaspersoft-library-cve-2025-10492-r6/
Restart Required: Yes
Instructions:
1. Monitor vendor advisory for patch release 2. Apply patch when available 3. Restart affected services 4. Verify fix implementation
🔧 Temporary Workarounds
Input Validation Filter
allImplement strict input validation to reject serialized objects from untrusted sources
Network Segmentation
allIsolate affected systems from internet and restrict internal network access
🧯 If You Can't Patch
- Implement web application firewall with deserialization attack detection rules
- Disable or remove vulnerable components if not essential for business operations
🔍 How to Verify
Check if Vulnerable:
Check application dependencies for Jaspersoft Library version and compare with vendor advisoryCheck Version:
Check application dependency files (pom.xml, build.gradle) or use: java -jar your-application.jar --versionVerify Fix Applied:
Test with safe deserialization payloads after implementing controls📡 Detection & Monitoring
