OVERVIEW¶
Reflected Cross Site Scripting (XSS) vulnerability.
DESCRIPTION¶
Due to an improper output encoding, a Reflected Cross-Site Scripting (XSS) attack can be carried out by an attacker injecting a malicious payload into some pages via a URL parameter.
IMPACT¶
By leveraging an XSS attack, a malicious actor can cause the browser to redirect to a malicious website, modify the UI of the webpage, retrieve information from the browser, or cause harm otherwise. However, since all session-related sensitive cookies are set with the httpOnly flag and protected against session hijacking or similar attacks, this is not a concern.
