CVE-2023-30556 | SQL injection in sql_optimize.py optimize_sqltuningadvisor method in Archery - GHSL-2022-107

Exp

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 `optimize_sqltuningadvisor` method of `sql_optimize.py`. User input coming from the `db_name` parameter value in `sql_optimize.py` is passed to the `sqltuningadvisor` method in `oracle.py`for execution. To mitigate escape the variables accepted via user input when used in `sql_optimize.py`. Users may also use prepared statements when dealing with SQL as a mitigation for this issue. This issue is also indexed as `GHSL-2022-107`.

Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
