CVE-2021-22852Network attack vector

Authenticated database disclosure via registration parameter

Published Jan 19, 2021 · Updated Sep 16, 2024

SQL injection in HGiga OAKlouds-mol_course_v3 2.0 and 3.0 allows remote authenticated users to read database schema and data. The online-registration page accepts a crafted URL parameter as SQL syntax rather than treating it solely as data; the parameter name and code locus are undisclosed. A valid user session is required, and the documented consequence is exposure of database structure and stored records.
