QID 984064

Affected versions of `pg` contain a remote code execution vulnerability that occurs when the remote database or query specifies a crafted column name. There are two specific scenarios in which it is likely for an application to be vulnerable: 1. The application executes unsafe, user-supplied sql which contains malicious column names. 2. The application connects to an untrusted database and executes a query returning results which contain a malicious column name. ## Proof of Concept ``` const { Client } = require('pg') const client = new Client() client.connect() const sql = `SELECT 1 AS "\\'/*", 2 AS "\\'*/\n + console.log(process.env)] = null;\n//"` client.query(sql, (err, res) => { client.end() }) ``` ## Recommendation * Version 2.x.x: Update to version 2.11.2 or later. * Version 3.x.x: Update to version 3.6.4 or later. * Version 4.x.x: Update to version 4.5.7 or later. * Version 5.x.x: Update to version 5.2.1 or later. * Version 6.x.x: Update to version 6.4.2 or later. ( Note that versions 6.1.6, 6.2.5, and 6.3.3 are also patched. ) * Version 7.x.x: Update to version 7.1.2 or later. ( Note that version 7.0.2 is also patched. )

Successful exploitation of this vulnerability may affect the confidentiality, integrity, and availability of the targeted user.
