Hunting for Fortinet's CVE-2024-21762 | Grey Noise Blog

Summary: GreyNoise researcher h0wdy developed a detection for CVE-2024-21762, an out-of-bounds write vulnerability in Fortinet FortiOS and FortiProxy, after the flaw was added to CISA's Known Exploited Vulnerabilities Catalog. No writeup or proof of concept was available, so the researcher had to gather enough information independently to build the detection for GreyNoise sensors.

What you should know: The vulnerability's addition to CISA's KEV Catalog means it is being exploited in the wild, yet defenders had no public writeup or proof of concept to work from - detection depended on one researcher reconstructing the attack from scratch.
