CVE-2025-8410 is a Use After Free (CWE-416) vulnerability identified in RTI Connext Professional's Security Plugins component, affecting versions from 7.5.0 up to but not including 7.6.0. The vulnerability arises due to improper memory management where a previously freed memory object is accessed, leading to undefined behavior that can be leveraged for file manipulation. This flaw can be exploited by an attacker with low privileges and local access, without requiring user interaction. The attack complexity is low, meaning exploitation does not require specialized conditions beyond access and privileges. The vulnerability impacts availability by potentially allowing attackers to disrupt normal operations through file manipulation, but it does not compromise confidentiality or integrity of data. The CVSS 4.0 vector (AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:N/VA:H/SC:N/SI:N/SA:N) reflects local attack vector, low complexity, partial authentication, no user interaction, and high impact on availability. No patches were linked at the time of publication, and no known exploits have been reported in the wild. RTI Connext Professional is widely used in real-time data distribution for industrial automation, defense, and critical infrastructure, making this vulnerability relevant for environments requiring high reliability and security.

For European organizations, especially those in industrial automation, manufacturing, defense, and critical infrastructure sectors, this vulnerability poses a risk of service disruption due to file manipulation enabled by the Use After Free flaw. Availability impacts could lead to downtime or degraded performance of real-time communication systems that rely on RTI Connext Professional, potentially affecting operational technology (OT) environments. Although confidentiality and integrity are not directly impacted, the disruption of availability in critical systems can have cascading effects on safety, production continuity, and compliance with regulatory requirements such as NIS2. The requirement for local access and partial privileges limits remote exploitation but elevates risk from insider threats or compromised local accounts. Organizations with extensive deployments of RTI Connext Professional should consider this vulnerability a medium risk that could affect operational resilience.

1. Apply patches or updates from RTI as soon as they become available to address this Use After Free vulnerability. 2. Restrict local access to systems running RTI Connext Professional to trusted personnel only, minimizing the risk of exploitation by low-privilege users. 3. Implement strict file system permissions and access controls to prevent unauthorized file manipulation. 4. Monitor system logs and file integrity for unusual activity indicative of exploitation attempts. 5. Employ endpoint detection and response (EDR) solutions to detect anomalous behavior related to memory corruption or file operations. 6. Conduct regular security audits and vulnerability assessments focusing on OT and real-time communication systems. 7. Segment networks to isolate critical RTI Connext Professional deployments from general IT environments, reducing attack surface. 8. Train staff on insider threat awareness and secure handling of privileged accounts to mitigate risks from partial privilege exploitation.
