Reflected XSS in FAST LTA Silent Brick WebUI before 2.63.04 allows remote authenticated users to execute JavaScript in a victim's browser. The WebUI reflects the h, hd, p, pi, s, t, x, and y request parameters into page output without sanitization or contextual encoding. Exploitation requires low-privileged WebUI access and a victim to load the crafted response, exposing session data and browser-mediated actions.
