CVE-2024-52061
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedBuffer Copy without Checking Size of Input ('Classic Buffer Overflow') vulnerability in RTI Connext Professional (Core Libraries, Queuing Service, Recording Service, Routing Service) allows Overflow Variables and Tags.This issue affects Connext Professional: from 7.4.0 before 7.5.0, from 7.0.0 before 7.3.0.5, from 6.1.0 before 6.1.2.21, from 6.0.0 before 6.0.1.40, from 5.0.0 before 5.3.1.45.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA classic buffer overflow vulnerability exists in RTI Connext Professional's Core Libraries, Queuing Service, Recording Service, and Routing Service. The flaw allows overflow of variables and tags due to insufficient bounds checking when copying data into fixed-size buffers. This critical flaw (CVSS 9.8) can potentially allow remote code execution or denial of service when processing malformed data.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify RTI Connext Professional installationLocate the RTI Connext installation directory, typically under $RTI_HOME or C:\rti_connext. Check for the 'rti_connext_professional' folder or search for 'rtiddscore' libraries (rti_<os>_<arch>.dll on Windows, librti_<os>_*.so on Linux).Affected if RTI Connext Professional is installed on the system.
-
Determine installed versionCheck the version file or product information. In the installation root, look for a version manifest, README, or execute 'rtiddsgen -version' if available. The version is often in the directory name (e.g., rti_connext_professional-7.3.0) or in a version.properties file.Affected if The installed version falls within any of these ranges: 5.0.0 to 5.3.1.44, 6.0.0 to 6.0.1.39, 6.1.0 to 6.1.2.20, 7.0.0 to 7.3.0.4, or 7.4.0 to 7.4.x.
-
Confirm vulnerable components are in useIdentify if any of these services are running or configured: Core Libraries (rti_<os>_<arch>.dll/lib), Queuing Service (rtiqueuingservice), Recording Service (rtirecordingservice), or Routing Service (rtiroutingservice). Check running processes or startup configurations for these executables.Affected if Any of the Core Libraries, Queuing Service, Recording Service, or Routing Service components are active.
-
Check for exposed DDS interfacesExamine the domain participant configuration XML files (usually in <installation>/resource/xml/ or user-defined paths) for <domain_participant> elements. Identify if DDS ports (typically UDP/UDPv6 ports 7400-7403 for default domains) are accessible from untrusted networks using tools like netstat or by reviewing firewall rules.Affected if DDS domain participants are configured and accessible over the network.
The system is affected if RTI Connext Professional version is below 7.5.0 (or below 7.3.0.5, 6.1.2.21, 6.0.1.40, or 5.3.1.45 depending on the major branch) and any of the vulnerable components (Core Libraries, Queuing, Recording, or Routing Service) are in use.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped5.3.1.456.0.1.406.1.2.21
Upgrade RTI Connext Professional to version 7.5.0, 7.3.0.5, 6.1.2.21, 6.0.1.40, or 5.3.1.45 or later. Apply network segmentation and input validation as temporary mitigations if immediate upgrade is not feasible.
Upgrade to Connext Professional 5.3.1.45 (5.x), 6.0.1.40 (6.0.x), 6.1.2.21 (6.1.x), or 7.3.0.5 (7.x) or later - choose the appropriate minor version that contains the fix for your current branch
- 1. Identify the currently installed Connext Professional version by checking the installation directory or running the version command specific to your deployment
- 2. Determine which version branch you are currently on (5.x, 6.0.x, 6.1.x, or 7.x)
- 3. Download the appropriate fixed version from the RTI customer portal or official distribution channels: for 5.x branch upgrade to 5.3.1.45 or later; for 6.0.x upgrade to 6.0.1.40 or later; for 6.1.x upgrade to 6.1.2.21 or later; for 7.x upgrade to 7.3.0.5 or later
- 4. Review RTI Connext Professional release notes for the target version to understand any compatibility considerations
- 5. Back up all existing Connext configurations, XML files, and persistent data
- 6. Stop all running Connext services (Core Libraries, Queuing Service, Recording Service, Routing Service) before upgrading
- 7. Install the upgraded version following the standard RTI installation procedure
- 8. Restore configurations from backup after installation
