SQL injection in sql/instance.py endpoint in Archery - GHSL-2022-101

Archery is an open source SQL audit platform. The Archery project contains multiple SQL injection vulnerabilities, that may allow an attacker to query the connected databases. Affected versions are subject to SQL injection in the sql/instance.py endpoint's describe method. In several cases, user input coming from the tb_name parameter value, the db_name parameter value or the schema_name value in the sql/instance.py describe endpoint is passed to the describe_table methods in given SQL engine implementations, which concatenate user input unsafely into a SQL query and afterwards pass it to the query method of each database engine for execution. Please take into account that in some cases all three parameter values are concatenated, in other only one or two of them. The affected methods are: describe_table in sql/engines/clickhouse.pywhich concatenates input which is passed to execution on the database in the query method in sql/engines/clickhouse.py, describe_table in sql/engines/mssql.py which concatenates input which is passed to execution on the database in the query methods in sql/engines/mssql.py, describe_table in sql/engines/mysql.pywhich concatenates input which is passed to execution on the database in the query method in sql/engines/mysql.py, describe_table in sql/engines/oracle.py which concatenates input which is passed to execution on the database in the query methods in sql/engines/oracle.py, describe_table in…
