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

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

Note that both these vulns involve interacting with an authenticated user. The “threat model” 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. It’s not uncommon to find creds like these in a corporate wiki or share somewhere.
