Technical details

A SQL injection vulnerability exists in Django's Oracle database backend. The root cause is improper neutralization of the 'tolerance' parameter within Geographic Information System (GIS) functions and aggregates. An attacker with low privileges can provide a specially crafted tolerance value to break out of SQL escaping and execute arbitrary SQL commands. This affects Django versions 1.11.x before 1.11.29, 2.2.x before 2.2.11, and 3.0.x before 3.0.4. Patches are available in versions 1.11.29, 2.2.11, and 3.0.4.

Affected products

  • Django Django >= 1.11, < 1.11.29; >= 2.2, < 2.2.11; >= 3.0, < 3.0.4
