Local service integrity compromise via malicious environment file
Published Dec 13, 2024 · Updated Feb 7, 2025
Stack buffer overflow in RTI Connext Professional Persistence Service allows local users to compromise service integrity via .environment files. On non-Windows systems, the service copies data parsed from a user-controlled .environment file to the stack without correctly bounding the write; affected releases are 5.3.1.40 before 5.3.1.41, 6.1.1.2 before 6.1.2.21, and 7.0.0 before 7.3.0.2. Exploitation requires write access to the service account's home-directory file and can alter service execution or interrupt the service.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=5.3.1.40 <5.3.1.41
- Affected versionversion=6.1.1.2 <6.1.2.21
- Affected versionversion=7.0.0 <7.3.0.2
