CVE-2025-1255
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 · uneditedUntrusted Pointer Dereference vulnerability in RTI Connext Professional (Core Libraries) allows Pointer Manipulation.This issue affects Connext Professional: from 7.4.0 before 7.6.0, from 7.2.0 before 7.3.0.9.
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 confidenceUntrusted Pointer Dereference vulnerability in RTI Connext Professional Core Libraries allows attackers to manipulate pointers by dereferencing untrusted input without validation. This memory corruption issue in the middleware could allow arbitrary memory read/write operations, potentially leading to remote code execution given the critical 9.1 CVSS score.

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 if RTI Connext Professional is installedSearch for RTI Connext installation directories such as C:\Program Files\RTI or /opt/rti_connext, or check for rti_* directories in common installation paths. Look for nddscore.dll (Windows) or libnddscore.so (Linux) which are core library files.Affected if RTI Connext Professional software is present on the system
-
Locate and identify the installed RTI Connext versionCheck the version.xml file typically found in the lib folder of the RTI installation (e.g., <install_dir>/ndds.7.x.x/lib/java/VERSION.txt or version.xml). On Windows, right-click nddscore.dll and view Properties > Details for version info. Alternatively, run 'rtiddsgen -version' if available.Affected if The installed version falls within >= 7.2.0 and < 7.3.0.9, OR >= 7.4.0 and < 7.6.0
-
Identify applications or services using RTI Connext librariesReview running processes for applications linked against RTI libraries (nddscore.dll, nddsc.dll, nddds.so). Check application configuration files for <rti_connext_install> paths or NDDSHOME environment variable references. Examine any middleware configuration files (.xml, .qos) that load RTI Connext.Affected if Applications or services are running that depend on RTI Connext Professional core libraries from an affected version
-
Verify the middleware is receiving external or untrusted network inputReview DDS domain participant configurations in application XML/QOS files. Check if the system participates in open DDS domains (default domain ID 0 or any exposed domain) where remote participants can publish data. Inspect firewall rules for DDS ports (typically 7400-7409 plus domain offset).Affected if The RTI Connext application listens on network domains accessible to untrusted participants, enabling external input to reach the core libraries
You are affected if RTI Connext Professional version 7.2.0 through 7.3.0.8, or 7.4.0 through 7.5.x, is installed and actively running with network exposure to untrusted DDS participants.

dbcve · scoped7.3.0.97.6.0
Upgrade RTI Connext Professional to version 7.6.0 or later (or 7.3.0.9+ for the 7.2.x branch) to patch the pointer validation flaw. Verify application compatibility after upgrade in a test environment before production deployment.
Connext Professional 7.3.0.9 (for 7.2.x branch) or 7.6.0 (for 7.4.x/7.5.x branch)
- 1. Identify your current Connext Professional version by checking the installed binaries or release documentation.
- 2. If you are on version 7.2.0 or later but before 7.3.0.9, plan to upgrade to version 7.3.0.9.
- 3. If you are on version 7.4.0 or later but before 7.6.0, plan to upgrade to version 7.6.0.
- 4. Download the appropriate fixed release from the official RTI download portal or support website.
- 5. Test the upgrade in a non-production environment first to verify compatibility with your application.
- 6. Review the release notes for the target version for any migration considerations.
- 7. Apply the upgrade to production systems after successful testing.
