CVE-2023-24010

8.2 HIGH

📋 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

Products:
  • ROS 2 (Robot Operating System 2)
  • DDS implementations with vulnerable PKCS#7 validation
  • Systems using sros2 security plugins
Versions: ROS 2 versions prior to fixes in 2023
Operating Systems: Linux, Windows, macOS - any OS running affected DDS implementations
Default Config Vulnerable: ⚠️ Yes
Notes: Systems using DDS security with PKCS#7 certificate validation are vulnerable. The issue affects the permission document verification process.

⚠️ 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).

  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. 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.

🌐 Internet-Facing: MEDIUM - While DDS systems are often internal, internet-facing endpoints could be targeted if exposed.
🏢 Internal Only: HIGH - DDS systems are commonly used in internal industrial, robotics, and IoT networks where compromise could have significant operational impact.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

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

all

Isolate DDS systems from untrusted networks and implement strict network access controls

Enhanced Certificate Validation

all

Implement 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

📡 Detection & Monitoring

Log Indicators:

  • Unusual certificate validation failures
  • Permission document modification events
  • Unexpected DDS participant connections

Network Indicators:

  • Unusual DDS traffic patterns
  • Certificate validation bypass attempts
  • Malformed PKCS#7 messages

SIEM Query:

Search for DDS security events with certificate validation errors or permission document changes
