CVE-2020-29653Public exploitNetwork attack vector

Reflected HTML injection via unvalidated login parameter

Published Apr 13, 2022 · Updated Aug 4, 2024

Reflected HTML injection in Froxlor 0.10.22 and earlier allows remote attackers to inject arbitrary markup into the login page. The login-page handler reflects the customermail GET value into its HTML response without validation; AntiXSS in 0.10.22 only partly filters this input. No account is required, but a victim must open a crafted request, after which injected tags alter displayed content or expose data through dangling markup without interrupting service.
