CVE-2025-10450
📋 TL;DR
CVE-2025-10450 is an exposure of private personal information vulnerability in RTI Connext Professional Core Libraries that allows unauthorized actors to sniff network traffic containing sensitive data. This affects Connext Professional versions from 7.4.0 before 7.* and from 7.2.0 before 7.3.1, potentially exposing any personal information transmitted via these libraries.
💻 Affected Systems
- RTI Connext Professional Core Libraries
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete exposure of all personal identifiable information (PII) transmitted through affected systems, leading to identity theft, regulatory violations, and reputational damage.
Likely Case
Partial exposure of sensitive data in transit, potentially including user credentials, personal details, or proprietary information that could be used for further attacks.
If Mitigated
Limited data exposure with encryption bypassed only for specific traffic patterns, still potentially revealing metadata or partial information.
🎯 Exploit Status
Exploitation requires network access to traffic path; no authentication or special privileges needed to intercept data.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 7.3.1 and later 7.* versions
Vendor Advisory: https://www.rti.com/vulnerabilities/#cve-2025-10450
Restart Required: Yes
Instructions:
1. Download latest patched version from RTI support portal. 2. Stop all Connext applications. 3. Install updated libraries. 4. Restart applications with patched libraries.
🔧 Temporary Workarounds
Network Segmentation
allIsolate Connext traffic to trusted network segments to limit exposure.
Application Layer Encryption
allImplement additional encryption at application level before Connext transmission.
🧯 If You Can't Patch
- Implement network-level encryption (IPsec, VPN) for all Connext traffic
- Restrict Connext communications to physically isolated or highly controlled network segments
🔍 How to Verify
Check if Vulnerable:
Check Connext library version using RTI version utilities or examine installed package versions.Check Version:
rtiddsgen -version or check installed package (rpm -qa | grep rti-connext or equivalent)Verify Fix Applied:
Verify installed Connext version is 7.3.1 or later 7.* versions, and test network traffic encryption.📡 Detection & Monitoring
Log Indicators:
- Unusual network traffic patterns
- Failed encryption handshakes
- Unexpected data access attempts
Network Indicators:
- Unencrypted Connext DDS traffic on network
- Suspicious packet capture activity on Connext ports
