Description

OpenSTAManager is an open source management software for technical assistance and invoicing. Prior to version 2.10.2, multiple AJAX select handlers in OpenSTAManager are vulnerable to Time-Based Blind SQL Injection through the options[stato] GET parameter. The user-supplied value is read from $superselect['stato'] and concatenated directly into SQL WHERE clauses as a bare expression, without any sanitization, parameterization, or allowlist validation. An authenticated attacker can inject arbitrary SQL statements to extract sensitive data from the database, including usernames, password hashes, financial records, and any other information stored in the MySQL database. This issue has been patched in version 2.10.2.
