CVE-2025-59954
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary code on Knowage servers by exploiting unsafe JXPathContext usage in MetaService.java. It affects all Knowage deployments running versions 8.1.26 or earlier. Attackers can achieve full system compromise without authentication.
💻 Affected Systems
- Knowage Server
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system takeover with attacker gaining root/admin privileges, data exfiltration, lateral movement, and persistent backdoor installation.
Likely Case
Remote code execution leading to service disruption, data theft, and deployment of cryptocurrency miners or ransomware.
If Mitigated
Limited impact with proper network segmentation and least privilege, potentially only affecting the Knowage application container.
🎯 Exploit Status
The advisory suggests exploitation is straightforward given the JXPathContext vulnerability pattern.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 8.1.27
Vendor Advisory: https://github.com/KnowageLabs/Knowage-Server/security/advisories/GHSA-96cv-75hg-xrgq
Restart Required: Yes
Instructions:
1. Backup your Knowage configuration and data. 2. Download version 8.1.27 from official repository. 3. Stop Knowage service. 4. Replace with patched version. 5. Restart Knowage service. 6. Verify functionality.
🔧 Temporary Workarounds
Network Isolation
linuxRestrict network access to Knowage server to only trusted IPs
iptables -A INPUT -p tcp --dport [Knowage_port] -s [trusted_network] -j ACCEPT
iptables -A INPUT -p tcp --dport [Knowage_port] -j DROP
WAF Rule
allImplement web application firewall rules to block JXPath injection patterns
🧯 If You Can't Patch
- Implement strict network segmentation and firewall rules to limit access to Knowage instances
- Deploy Knowage in isolated containers with minimal privileges and monitor for suspicious activity
🔍 How to Verify
Check if Vulnerable:
Check Knowage version in web interface or configuration files, or run: find / -name "*knowage*" -type f | xargs grep -l "8.1"Check Version:
grep -r "version" /opt/knowage/ 2>/dev/null | grep -i "8.1"Verify Fix Applied:
Verify version is 8.1.27 or higher in admin interface or by checking pom.xml for version tag📡 Detection & Monitoring
Log Indicators:
- Unusual JXPath-related errors in Knowage logs
- Suspicious Java process spawning
- Unexpected network connections from Knowage server
Network Indicators:
- Unusual outbound connections from Knowage server
- Traffic patterns indicating reverse shells or command execution
SIEM Query:
source="knowage.log" AND ("JXPath" OR "MetaService" OR "java.lang.Runtime")
