Unauthenticated sysadmin creation via exposed authorization token
Published Feb 6, 2022 · Updated Aug 3, 2024
Improper authentication in Servisnet Tessa 0.0.2 allows remote attackers to create a sysadmin account through a crafted HTTP request. The client-side app.js exposes a default Authorization header for the ms_user identity, and the server accepts that identity on the users endpoint without authentication. Network access to the HTTPS application is sufficient to submit a users POST request that creates a persistent administrator account with full application privileges.
