# Impact :
***********
OneSource Consultoria Informatica Coimbra Portugal is prone to an SQL-injection
vulnerability because it fails to sufficiently sanitize user-supplied data before using
it in an SQL query. Exploiting this issue could allow an attacker to compromise the
application, access or modify data, or exploit latent vulnerabilities in the underlying database.
A remote attacker can send a specially crafted request to the vulnerable application and
execute arbitrary SQL commands in application`s database. Further exploitation of this
vulnerability may result in unauthorized data manipulation.
An attacker can exploit this issue using a browser or with any SQL Injector Tool.

Reflected XSS (or Non-Persistent) :
***************************************
The server reads data directly from the HTTP
request and reflects it back in the HTTP response. Reflected XSS exploits occur when an
attacker causes a victim to supply dangerous content to a vulnerable web application,
which is then reflected back to the victim and executed by the web browser. The most common
mechanism for delivering malicious content is to include it as a parameter in a URL that is
posted publicly or e-mailed directly to the victim. URLs constructed in this manner constitute
the core of many phishing schemes, whereby an attacker convinces a victim to visit a URL
that refers to a vulnerable site. After the site reflects the attacker's content back to the victim,
the content is executed by the victim's browser.
