Flowise | <= 2.2.3 How the Exploit Works

The vulnerability stems from the inappropriate handling of the ‘tableName’ parameter in Postgres_VectorStores within Flowise. An attacker can manipulate this parameter to inject malicious SQL commands. These commands are then executed by the database, leading to unauthorized access, data corruption, or even full system takeover.

Conceptual Example Code

Below is a conceptual example of how this vulnerability might be exploited.

POST /Postgres_VectorStores HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
tableName=users; DROP TABLE users; --

In this example, the attacker sends a POST request with a malicious payload. The ‘tableName’ parameter is exploited to drop the ‘users’ table, resulting in potential data loss.

Mitigation Guidance

Organizations are advised to apply the patch provided by the vendor immediately. In cases where immediate patching is not possible, implementation of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) may serve as a temporary mitigation strategy, helping to prevent the exploitation of this vulnerability in the interim.
