Four months later on CVE-2023-21716 - I still haven't seen a single in the wild document that reaches RCE for this, nor an RCE exploit.

#CVE202321716

Haven't seen any working exploitation of #CVE202321716 at all - all just people reusing the crash POC, nobody made it to RCE.

I've been keeping an eye on #CVE202321716 (the MS Word RTF vuln) via #GossiMonitoring

The headline is, people are starting to experiment with it.

Keep an eye on CVE-2023-21716 aka MS Word vulnerability from February 2023 in RTF files.

There's a public proof of concept: https://qoop.org/publications/cve-2023-21716-rtf-fonttbl.md

Where it gets more interesting - you can embed RTF files in email, Microsoft Outlook renders them with no clicks, by just reading the email. There's a decent chance this could become problematic combination.. although not yet as the PoC is vague enough to require a clue to exploit. HT @fellows
