Script execution via unsanitized login path

Published May 17, 2023 · Updated Jan 22, 2025

Reflected XSS in Exelysis Unified Communication Solution 1.0 allows remote attackers to execute arbitrary script through the eucsAdmin login URL path. The login page writes an unsanitized request path into the form action attribute, letting markup break out and run HTML or JavaScript in the affected site's context. Exploitation is unauthenticated but requires a user to follow the crafted URL; executed script can read or alter browser-accessible data.
