Technical details
The vulnerability occurs when the application receives a POST request, where it ignores the request's Content-Length header and leaves the POST body on the TCP/TLS socket.

Impact

Mitigation and workarounds
Affected users should upgrade to versions newer than 9.115 of Pulse Secure products. The vendor has released security advisories with detailed mitigation information (Vendor Advisory).
