CVE-2024-52065
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 · uneditedBuffer Copy without Checking Size of Input ('Classic Buffer Overflow') vulnerability in RTI Connext Professional on non-Windows (Persistence Service) allows Buffer Overflow via Environment Variables.This issue affects Connext Professional: from 7.0.0 before 7.3.0.2, from 6.1.1.2 before 6.1.2.21, from 5.3.1.40 before 5.3.1.41.
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 confidenceA classic buffer overflow vulnerability exists in the RTI Connext Professional Persistence Service on non-Windows platforms. The vulnerability stems from insufficient bounds checking when copying data from environment variables into fixed-size buffers, allowing an attacker to overflow the buffer and potentially execute arbitrary code or cause denial of service.

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 RTI Connext Professional versionLocate the RTI Connext Professional installation directory and check the version information file or use the rtiddsversion utility if available in the installationAffected if The installed version falls within any of these ranges: >= 6.1.1.2 and < 6.1.2.21; >= 7.0.0 and < 7.3.0.2; or exactly 5.3.1.40
-
Confirm non-Windows platformCheck the operating system where RTI Connext is installed using 'uname -a' or 'systeminfo' commandsAffected if The system is running a non-Windows platform (Linux, Solaris, AIX, etc.) since this vulnerability only affects non-Windows platforms
-
Determine if Persistence Service is enabledCheck the RTI Connext configuration files or running processes for the Persistence Service component (rtipersistence service or similar process name)Affected if The Persistence Service is enabled, configured, or running as the vulnerability exists specifically in this component
-
Inspect environment variables used by Persistence ServiceReview environment variables that may be read by the Persistence Service, particularly those controlling service behavior, paths, or configurationAffected if Environment variables containing user-controlled data are set and being used by the Persistence Service, as the buffer overflow occurs when copying from these variables into fixed-size buffers
A user is affected if they are running a vulnerable version of RTI Connext Professional on a non-Windows platform with the Persistence Service enabled and environment variables configured, since the buffer overflow requires the Persistence Service to read data from environment variables.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped6.1.2.217.3.0.2
Upgrade RTI Connext Professional to version 7.3.0.2, 6.1.2.21, or 5.3.1.41 or later respectively. If immediate patching is not feasible, restrict access to systems running the Persistence Service and audit environment variable configurations.
Upgrade to Connext Professional 5.3.1.41, 6.1.2.21, or 7.3.0.2 (whichever corresponds to your current major version branch)
- 1. Identify the currently installed RTI Connext Professional version and confirm it matches the affected versions (5.3.1.40, 6.1.1.2 through 6.1.2.20, or 7.0.0 through 7.3.0.1)
- 2. If running on a non-Windows platform and using Persistence Service, verify the specific environment variables being passed to the service
- 3. Download the appropriate fixed version from the official RTI download portal: 5.3.1.41, 6.1.2.21, or 7.3.0.2
- 4. Stop all running RTI Connext processes, including Persistence Service
- 5. Install the upgraded version following RTI's standard installation procedures
- 6. Restart Connext services and verify Persistence Service operates normally
- 7. Validate that the environment variables are now properly validated before use
