Official description
ScadaLTS 2.8.1-release-candidate build 0 is affected by an Authenticated Blind SQL Injection
The /api/events/search endpoint accepts a JSON body containing a sortBy array. The values in this array are concatenated directly into the SQL ORDER BY clause without any sanitization or parameterization. This allows authenticated users with the ROLE_USER role to perform time-based and boolean-based blind SQL injection to extract arbitrary data from the database, including password hashes of all users.
The endpoint is accessible to any authenticated user with ROLE_USER, ROLE_ADMIN, or ROLE_PUBLIC via POST /api/events/search as defined in spring-security.xml.
Weakness: CWE-89
