CVSS v3.1

Official Description

eProsima Fast DDS (formerly Fast RTPS) is a C++ implementation of the Data Distribution Service standard of the Object Management Group. Prior to versions 2.13.0, 2.12.2, 2.11.3, 2.10.3, and 2.6.7, an invalid DATA_FRAG Submessage causes a bad-free error, and the Fast-DDS process can be remotely terminated. If an invalid Data_Frag packet is sent, the `Inline_qos, SerializedPayload` member of object `ch` will attempt to release memory without initialization, resulting in a 'bad-free' error. Versions 2.13.0, 2.12.2, 2.11.3, 2.10.2, and 2.6.7 fix this issue.

Risk Analysis

A memory management error in eProsima Fast DDS occurs when processing invalid DATA_FRAG submessages, which can lead to a process crash. This critical flaw allows for remote termination of the service.

No public exploit is known, and it is not in the CISA KEV. The flaw is remotely exploitable.

Recommended Action

Update to Fast DDS versions 2.13.0, 2.12.2, 2.11.3, 2.10.2, or 2.6.7 to resolve the memory handling issue.

Technical Analysis

CVE-2023-50716 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.

From a weakness classification perspective (CWE-416): Use-after-free vulnerabilities involve accessing memory after it has been freed, often enabling arbitrary code execution.
