CVE-2025-8410 is a Use After Free (UAF) vulnerability identified in RTI Connext Professional, specifically within its Security Plugins component. The affected versions range from 7.5.0 up to but not including 7.6.0. A Use After Free vulnerability occurs when a program continues to use a pointer after the memory it points to has been freed, potentially leading to undefined behavior such as memory corruption, crashes, or arbitrary code execution. In this case, the vulnerability allows for file manipulation, which suggests that an attacker could exploit the flaw to alter files or file contents in an unauthorized manner. The CVSS 4.0 base score is 5.8, indicating a medium severity level. The vector details reveal that the attack requires local access (AV:L), low attack complexity (AC:L), privileges (PR:L), but no user interaction (UI:N). The vulnerability impacts confidentiality and availability at a high level (VC:H, VA:H), but not integrity (VI:N). The scope remains unchanged (S:U), and there are no known exploits in the wild as of the published date (September 23, 2025). RTI Connext Professional is a middleware product used for real-time data connectivity, often in critical systems such as industrial automation, defense, aerospace, and automotive sectors. The Security Plugins component likely handles encryption, authentication, or other security-related processing, making this vulnerability particularly sensitive. Exploiting this flaw could allow an attacker with local access and low privileges to manipulate files, potentially disrupting system operations or bypassing security controls. Given the nature of the product, such exploitation could have serious consequences in environments relying on real-time data integrity and availability.

For European organizations, especially those operating in critical infrastructure sectors such as manufacturing, transportation, aerospace, and defense, this vulnerability poses a significant risk. RTI Connext Professional is commonly used in real-time systems where data integrity and availability are paramount. File manipulation through this vulnerability could lead to system downtime, data corruption, or unauthorized modification of security configurations. This could disrupt industrial control systems, delay critical operations, or expose sensitive data. The requirement for local access and low privileges means that insider threats or attackers who have gained limited footholds could escalate their impact. The high impact on confidentiality and availability could result in operational disruptions and potential breaches of regulatory compliance, such as GDPR, if personal data is affected. Although no known exploits exist yet, the medium severity and the nature of the vulnerability warrant proactive mitigation to prevent exploitation in sensitive European environments.

1. Immediate patching: Although no patch links are provided in the data, organizations should monitor RTI's official channels for security updates or patches addressing CVE-2025-8410 and apply them promptly once available. 2. Access control tightening: Restrict local access to systems running RTI Connext Professional to trusted personnel only, employing strict user privilege management to minimize the risk of exploitation by low-privilege users. 3. Network segmentation: Isolate systems using RTI Connext Professional within secure network segments to reduce the attack surface and limit lateral movement opportunities. 4. Runtime monitoring: Deploy host-based intrusion detection systems (HIDS) and file integrity monitoring tools to detect unusual file manipulations or memory corruption attempts related to the vulnerability. 5. Incident response readiness: Prepare and test incident response plans focusing on insider threats and local privilege escalation scenarios, ensuring rapid containment if exploitation is suspected. 6. Code auditing and hardening: For organizations developing custom extensions or plugins for RTI Connext, conduct thorough code reviews to detect and remediate similar memory management issues. 7. Vendor engagement: Engage with RTI for detailed technical guidance and timelines for patches or mitigations, and participate in security advisories to stay informed.
