Security Bulletin
This security bulletin contains one medium risk vulnerability.
EUVDB-ID: #VU24846
Risk: Medium
CVSSv3.1: 5.1 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L/E:P/RL:O/RC:C]
CVE-ID: CVE-2020-7471
CWE-ID:
CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to execute arbitrary SQL queries in database.
The vulnerability exists due to insufficient sanitization of user-supplied data if untrusted data is used as a StringAgg delimiter (e.g., in Django applications that offer downloads of data as a series of rows with a user-specified column delimiter). By passing a suitably crafted delimiter to a contrib.postgres.aggregates.StringAgg instance, it was possible to break escaping and inject malicious SQL in Django 1.11 before 1.11.28, 2.2 before 2.2.10, and 3.0 before 3.0.3. A remote attacker can send a specially crafted request to the affected application and execute arbitrary SQL commands within the application database.
Successful exploitation of this vulnerability may allow a remote attacker to read, delete, modify data in database and gain complete control over the affected application.
MitigationInstall update from vendor's website.
Vulnerable software versionsDjango: 1.11 - 3.0.2
