Vulnerability Disclosure
R7-2017-06 | CVE-2017-5241: Biscom SFT XSS (FIXED)
Summary
The Workspaces component of Biscom Secure File Transfer (SFT) version 5.1.1015
is vulnerable to stored cross-site scripting in two fields. An attacker would
need to have the ability to create a Workspace and entice a victim to visit the
malicious page in order to run malicious Javascript in the context of the
victim's browser. Since the victim is necessarily authenticated, this can allow
the attacker to perform actions on the Biscom Secure File Transfer instance on
the victim's behalf.

Cross-site Scripting (XSS) Attacks vs SQL Injection Attacks (SQLi)
A common misunderstanding in the world of Web Application Security is the
difference between the consequences of a cross-site scripting
