Technical details

A SQL injection vulnerability exists in OpenProject's cost reporting module within 'modules/reporting/lib/report/operator.rb'. The '=n' operator utilizes the 'parse_number_string' function, which fails to sanitize SQL metacharacters before embedding user-supplied input directly into a WHERE clause. An authenticated attacker with access to cost reports can provide malicious input via filter parameters to execute arbitrary SQL queries. This can result in unauthorized data exfiltration, modification, or deletion. The issue is resolved in version 17.2.3 by implementing proper parameterization in the SQL query.
