CVE-2020-23050Public exploitNetwork attack vector

Persistent page manipulation via unneutralized account fields

Published Oct 22, 2021 · Updated Aug 4, 2024

HTML injection in TAO Open Source Assessment Platform 3.3.0 RC02 allows remote authenticated users to alter pages via crafted account fields. The user edit endpoint stores unneutralized HTML from userFirstName and other account fields, then renders it in the Manage Users listing. A privileged account and a victim viewing that listing are required; exploitation enables persistent phishing, redirects, and module manipulation.
