Technical details

An Improper Restriction of XML External Entity Reference (XXE) vulnerability (CWE-611) exists in the Core Libraries of RTI Connext Professional. The flaw occurs during the processing of serialized data, where the library fails to properly restrict external entity references. A remote, unauthenticated attacker can exploit this by sending malicious XML-based serialized data over the network. Successful exploitation can lead to the disclosure of sensitive local files, server-side request forgery (SSRF), or a denial-of-service (DoS) condition. The issue affects multiple versions across the 4.x, 5.x, 6.x, and 7.x release branches; users are advised to upgrade to the latest patched versions (e.g., 7.3.1.1 or 7.7.0) as specified in the vendor advisory.
