CVE-2023-24010
📋 TL;DR
This vulnerability allows attackers with valid certificates to craft malicious DDS Participants or ROS 2 Nodes that can compromise secure DDS databus systems. The issue stems from improper PKCS#7 certificate validation in some DDS implementations, specifically misuse of OpenSSL's PKCS7_verify function. Systems using vulnerable DDS implementations with ROS 2 or other DDS-based middleware are affected.
💻 Affected Systems
- ROS 2 (Robot Operating System 2)
- DDS implementations with vulnerable PKCS#7 validation
- Systems using sros2 security plugins
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of the DDS databus system, allowing attackers to intercept, modify, or inject messages, potentially leading to full system control in critical infrastructure or robotics applications.
Likely Case
Unauthorized access to secure DDS communications, enabling data exfiltration, message manipulation, or denial of service against the databus.
If Mitigated
Limited impact with proper certificate validation and network segmentation, though some risk remains if certificates are compromised.
🎯 Exploit Status
Exploitation requires valid certificates but improper validation allows crafted malicious certificates to bypass security controls. Attackers need some initial access to certificate infrastructure.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check ROS 2 and DDS vendor updates from 2023 onward
Vendor Advisory: https://github.com/ros2/sros2/issues/282
Restart Required: No
Instructions:
1. Update ROS 2 to patched versions. 2. Update DDS middleware implementations. 3. Verify PKCS#7 validation implementations follow proper security practices. 4. Review and update certificate validation configurations.
🔧 Temporary Workarounds
Network Segmentation
allIsolate DDS systems from untrusted networks and implement strict network access controls
Enhanced Certificate Validation
allImplement additional certificate validation checks beyond PKCS#7 verification
🧯 If You Can't Patch
- Implement strict network segmentation to isolate DDS systems
- Monitor for unusual certificate usage or permission document changes
- Use application-level encryption in addition to DDS security
🔍 How to Verify
Check if Vulnerable:
Check if your DDS implementation uses OpenSSL PKCS7_verify for certificate validation and review permission document verification code
Check Version:
ros2 --version (for ROS 2 systems) or check DDS middleware version
Verify Fix Applied:
Verify that certificate validation properly checks all required fields and follows PKCS#7 security best practices
