Database disclosure via unbound api_id query

Published Nov 7, 2023 · Updated Sep 5, 2024

Blind SQL injection in Tyk Gateway 5.0.3 allows remote authenticated users to read database contents through a crafted api_id value. The /api/errors/count handler incorporates the api_id query parameter into a database query without safely binding the value. Exploitation requires a valid web session cookie, and the demonstrated consequence is disclosure of database contents.
