Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

CVE-2018-20061

Severity High
Score 7.5/10

Summary

A SQL injection issue was discovered in ERPNext 10.x and 11.x through 11.0.3-beta.29. This attack is only available to a logged-in user; however, many ERPNext sites allow account creation via the web. No special privileges are needed to conduct the attack. By calling a JavaScript function that calls a server-side Python function with carefully chosen arguments, a SQL attack can be carried out which allows SQL queries to be constructed to return any columns from any tables in the database. This is related to /api/resource/Item?fields= URIs, frappe.get_list, and frappe.call.

CWE-89 - SQL Injection

Structured Query Language (SQL) injection attacks are one of the most common types of vulnerabilities. They exploit weaknesses in vulnerable applications to gain unauthorized access to backend databases. This often occurs when an attacker enters unexpected SQL syntax in an input field. The resulting SQL statement behaves in the background in an unintended manner, which allows the possibility of unauthorized data retrieval, data modification, execution of database administration operations, and execution of commands on the operating system.
