CVE-2021-45422Public exploitNetwork attack vector

Unauthenticated browser script execution via reflected count parameter

Published Jan 13, 2022 · Updated Jul 9, 2026

Reflected cross-site scripting in Reprise License Manager 14.2 allows remote attackers to execute script via an unauthenticated GET request. The /goform/activate_process handler reflects the count parameter without neutralizing script markup, causing supplied JavaScript to run when the crafted response is viewed. Exploitation requires user interaction with an attacker-crafted URL, and the script executes within the RLM web-interface origin.
