CVE-2022-25767
📋 TL;DR
CVE-2022-25767 is a critical remote code execution vulnerability in the uReport2 console component. It allows attackers to execute arbitrary code by tricking the application into connecting to a malicious database server, leading to arbitrary file reads and deserialization attacks. All organizations using vulnerable versions of uReport2 are affected.

- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise allowing attackers to execute arbitrary commands, steal sensitive data, deploy ransomware, or pivot to other systems in the network.
Likely Case
Data exfiltration, credential theft, and installation of backdoors or cryptocurrency miners on affected systems.
If Mitigated
Limited impact through network segmentation and proper access controls, potentially only affecting isolated reporting systems.
🎯 Exploit Status
Public proof-of-concept code exists, and exploitation requires minimal technical skill. The vulnerability is in a widely used reporting component.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: None available
Vendor Advisory: No official vendor advisory found
Restart Required: No
Instructions:
No official patch exists. Remove or disable the vulnerable component entirely. Consider alternative reporting solutions.
🔧 Temporary Workarounds
Network Segmentation
linuxRestrict database server connections to only trusted, internal database servers using firewall rules.
iptables -A OUTPUT -p tcp --dport 3306 -d trusted_db_ip -j ACCEPT
iptables -A OUTPUT -p tcp --dport 3306 -j DROP
Disable Vulnerable Component
allRemove or disable the uReport2 console component from production systems.
Remove ureport2-console.jar from classpath or disable in application configuration
🧯 If You Can't Patch
- Implement strict network controls to prevent uReport2 from connecting to untrusted database servers
- Deploy application-level firewalls or WAFs to monitor and block suspicious database connection attempts
🔍 How to Verify
Check if Vulnerable:
Check if com.bstek.ureport:ureport2-console is in your project dependencies (Maven pom.xml or Gradle build.gradle) or deployed JAR files.Check Version:
mvn dependency:tree | grep ureport2-console OR find . -name "*ureport2*" -type fVerify Fix Applied:
Verify the component has been removed from your application and no longer appears in dependency scans or deployed files.📡 Detection & Monitoring
Log Indicators:
- Unexpected database connection attempts to unknown IP addresses
- Java deserialization errors or stack traces in application logs
- Unusual process execution from Java applications
Network Indicators:
- Outbound database connections from reporting systems to unfamiliar IPs
- Unusual data exfiltration patterns from reporting servers
SIEM Query:
source="application.logs" AND ("ureport2" OR "com.bstek.ureport") AND ("database connection" OR "deserialization")
