Descriptions

In Django 2.2 before 2.2.20, 3.0 before 3.0.14, and 3.1 before 3.1.8, MultiPartParser allowed directory traversal via uploaded files with suitably crafted file names. Built-in upload handlers were not affected by this vulnerability.

En Django versiones 2.2 anteriores a 2.2.20, versiones 3.0 anteriores a 3.0.14 y versiones 3.1 anteriores a 3.1.8, MultiPartParser permitía un salto de directorio por medio de archivos cargados con nombres de archivo adecuadamente diseñados. Los controladores de carga integrados no están afectados por esta vulnerabilidad

A flaw was found in Django. This flaw allows an attacker to upload specially-named files and exploit a flaw in the `MultiPartParser()` function to traverse directories. The highest threat from this vulnerability is to confidentiality.
