In RTI Connext Professional 5.3.1 through 6.1.0 before 6.1.1, a buffer overflow in XML parsing from Routing Service, Recording Service, Queuing Service, and Cloud Discovery Service allows attackers to execute code with the affected service's privileges, compromise the service's integrity, leak sensitive information, or crash the service. These attacks could be done via a remote malicious RTPS message; a compromised call with malicious parameters to the RTI_RoutingService_new, rti::recording::Service, RTI_QueuingService_new, or RTI_CDS_Service_new public APIs; or a compromised local file system containing a malicious XML file.
This vulnerability carries a HIGH severity rating with a CVSS v3.1 score of 7.3, requiring local system access to exploit with relatively low complexity without requiring user interaction requiring only low-level privileges . The vulnerability impacts limited data confidentiality, integrity (unauthorized modifications), and availability (service disruption) for affected systems. Impacting 1 product from rti organizations running these solutions should prioritize assessment and patching.
Reported in 2024, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For rti's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
