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

CVE-2019-14234

High
9.8/10

Summary

An issue was discovered in Django versions 1.8a1 through 1.11.22, 2.0a1 through 2.1.10, and 2.2a1 through 2.2.3. Due to an error in shallow key transformation, key and index lookups for "django.contrib.postgres.fields.JSONField", and key lookups for "django.contrib.postgres.fields.HStoreField", were subject to SQL Injection. This could, for example, be exploited via crafted use of "OR 1=1" in a key or index name to return all records, using a suitably crafted dictionary, with dictionary expansion, as the "**kwargs" passed to the "QuerySet.filter()" function.

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.
