Sorry for the copied text earlier.

According to the Safebreach report, CVE-2023-42757 was reported to the MSRC. Microsoft acknowledged the issues and took the following action:
Process Explorer Unprivileged DOS for Anti-Analysis (CVE-2023-42757): The vulnerability was reproduced, confirmed, and fixed by the engineering team of Process Explorer in version 17.04. CVE-2023-42757 was reserved for this vulnerability by MITER. MITER confirmed the vulnerability with Microsoft and will publish the CVE once online publication of the details is available.
Could you use the microsoft:sysinternals cpe or the microsoft:sysinternals_process_monitor cpe?
We would appreciate it very much.
Best Regards,

Process Explorer and Process Monitor are not the same software. It looks like microsoft:sysinternals: is the closest of the current CPEs. However, we still expect to see a new CPE by NIST in the future for this enrtry.
