GeoTools OGC Filter SQL Injection Vulnerabilities

Impact

GeoTools includes support for OGC Filter expression language parsing, encoding and execution against a range of datastore.

SQL Injection Vulnerabilities have been found when executing OGC Filters with JDBCDataStore implementations:

PropertyIsLike filter
- Requires PostGIS DataStore with "encode functions" enabled
- Or any JDBCDataStore (all relational databases) with String field (no mitigation)
strEndsWith function
- Requires PostGIS DataStore with "encode functions" enabled
strStartsWith function
- Requires PostGIS DataStore with "encode functions" enabled
FeatureId filter
- Requires JDBCDataStore (all relational databases) with prepared statements disabled and table with String primary key (Oracle not affected, SQL Server and MySQL have no settings to enabled prepared statements, PostGIS does)
jsonArrayContains function
- Requires PostGIS and Oracle DataStore with String or JSON field
DWithin filter
- Happens only in Oracle DataStore, no mitigation

Patches

GeoTools 28.2
GeoTools 27.4
GeoTools 26.7
GeoTools 25.7
GeoTools 24.7

Workarounds

Partial mitigation:

In PostGIS DataStore disable "encode functions"
In any PostGIS enable "prepared statements" (only database with such settings)

Map<String, Object> params = new HashMap<>(); params.put("dbtype", "postgis"); params.put("host", "localhost"); params.put("port", 5432); params.put("schema", "public"); params.put("database", "database"); params.put("user", "postgres"); params.put("passwd", "postgres"); params.put("preparedStatements", true ); // mitigation params.put("encode functions", false ); // mitigation DataStore dataStore = DataStoreFinder.getDataStore(params);
