CVE-2022-3225
📋 TL;DR
This vulnerability in Budibase allows attackers to execute arbitrary code by exploiting improper control of dynamically-managed code resources. It affects all Budibase deployments running versions prior to 1.3.20, potentially leading to remote code execution.
💻 Affected Systems
- Budibase
📦 What is this software?
Budibase by Budibase
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete system compromise, data exfiltration, and lateral movement within the network.
Likely Case
Unauthorized code execution allowing attackers to access sensitive data, modify application behavior, or establish persistence.
If Mitigated
Limited impact with proper network segmentation and minimal privileges, potentially only affecting the Budibase application container.
🎯 Exploit Status
Exploit details are publicly available through the huntr.dev bounty report. The vulnerability requires no authentication and has straightforward exploitation.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.3.20 and later
Vendor Advisory: https://github.com/budibase/budibase/commit/d35864be0854216693a01307f81ffcabf6d549df
Restart Required: Yes
Instructions:
1. Update Budibase to version 1.3.20 or later using your deployment method (Docker, Kubernetes, etc.). 2. Restart the Budibase service/container. 3. Verify the update was successful by checking the version.
🔧 Temporary Workarounds
Network Isolation
linuxRestrict network access to Budibase instances to only trusted IPs/networks
Use firewall rules to limit access: iptables -A INPUT -p tcp --dport 10000 -s trusted_network -j ACCEPT
iptables -A INPUT -p tcp --dport 10000 -j DROP
🧯 If You Can't Patch
- Implement strict network access controls to limit exposure
- Deploy web application firewall (WAF) rules to block suspicious code execution attempts
🔍 How to Verify
Check if Vulnerable:
Check Budibase version via web interface or API endpoint. Versions below 1.3.20 are vulnerable.Check Version:
curl -s http://budibase-host:port/api/version | grep versionVerify Fix Applied:
Confirm version is 1.3.20 or higher and test that code execution attempts are blocked.📡 Detection & Monitoring
Log Indicators:
- Unusual code execution patterns in application logs
- Suspicious file creation/modification events
- Unexpected process spawns from Budibase
Network Indicators:
- Unusual outbound connections from Budibase server
- Traffic patterns indicating code execution payloads
SIEM Query:
source="budibase" AND (event="code_execution" OR event="file_creation" OR process_name="unusual")
