Security Bulletin

This security bulletin contains one medium risk vulnerability.

1) SQL injection

EUVDB-ID: #VU24846

Risk: Medium

CVSSv4.0: 2.9 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P/U:Green]

CVE-ID: CVE-2020-7471

CWE-ID: CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Exploit availability: Yes

Description

The 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.

Mitigation

Update the affected package to version: 1:1.10.7-2+deb9u8, 1:1.11.28-1~deb10u1.

Vulnerable software versions

python-django (Debian package): 1:1.10.1-1 - 1:1.11.27-1~deb10u1
