CVE ID    : CVE-2019-17655

CVE ID    : CVE-2019-17655

Summary

A cleartext storage in a file or on disk (CWE-313) vulnerability in FortiOS SSL
VPN may allow an attacker to retrieve a logged-in SSL VPN user's credentials
should that attacker be able to read the session file stored on the targeted
device's system.


To successfully exploit this weakness, another unrelated weakness (eg: a system
file leaking vulnerability) would therefore need to be exploited first.
