Description

The Pulse Connect Secure appliance before 9.1R9 suffers from an uncontrolled gzip extraction vulnerability
which allows an attacker to overwrite arbitrary files, resulting in Remote Code Execution as root.
Admin credentials are required for successful exploitation.
Of note, MANY binaries are not in `$PATH`, but are located in `/home/bin/`.
