# CVE-2020-14943

# Description: The "Firstname" and "Lastname" parameters in Global RADAR BSA Radar 1.6.7234.X 
# are vulnerable to a stored Cross-Site Scripting (XSS) via the Update User Profile feature 
# (in the top-right of the application).

# Proof of Concept:

Using the "update user profile" feature in the top-right of the application while logged in, 
a malicious user can inject malicious, unencoded scripts, such as "<script>alert(1)</script>", 
into the Firstname and Lastname parameters of a user account. This stored XSS will execute on 
nearly every application page as these parameters are always present while logged in. This attack 
can be further leveraged by utilizing an existing authorization bypass exploit (CVE-2020-14944) 
to inject stored XSS payloads into these parameters for arbitrary existing user accounts.
