Researchers wrote this one up at <https://www.gosecure.net/blog/2020/08/26/forget-your-perimeter-rce-in-pulse-connect-secure/&gt;.

In CVE-2020-15408, I was musing about SSRF-to-RCE potential as a normal user, but this just skips right to CSRFโ€™ing an admin to get RCE.

Note that both these vulns involve interacting with an authenticated user. The โ€œthreat modelโ€ is different from that of previous Pulse Secure RCEs. Patch this but also invest in security training for your users!

ETA: This is otherwise post-auth RCE, so if you have admin creds, you can execute commands all the same. Itโ€™s not uncommon to find creds like these in a corporate wiki or share somewhere.
