HTML injection via signin username parameter

Published Oct 8, 2021 · Updated Aug 4, 2024

HTML injection in Verint Workforce Optimization 15.2.5.1033 allows remote attackers to inject markup through the /wfo/control/signin username parameter. The signin endpoint reflects the username value without adequate output encoding, allowing attacker-controlled HTML to reach the authentication page. The issue is remotely reachable without authentication and is bounded to integrity impact from altered page content; no confidentiality or service-interruption impact is reported.
