CVE-2020-13254: An issue was discovered in Django 2.2 before 2.2.13 and 3.0 before 3.0.7.

Noroxi assessment

Priority: Monitor (action score 25/100)

Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
Probability of exploitation in the next 30 days: 6% (FIRST EPSS); higher than 93.4% of all records.
Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
Fixed version: py3-django (Alpine:v3.13) 3.0.7-r0; python-django (Debian:10) 1:1.11.29-1~deb10u1; python-django (Debian:12) 2:2.2.13-1.
Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to py3-django (Alpine:v3.13) 3.0.7-r0; python-django (Debian:10) 1:1.11.29-1~deb10u1; python-django (Debian:12) 2:2.2.13-1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

An issue was discovered in Django 2.2 before 2.2.13 and 3.0 before 3.0.7. In cases where a memcached backend does not perform key validation, passing malformed cache keys could result in a key collision, and potential data leakage.

Root cause

A certificate validation error is silently swallowed instead of terminating the connection. Often, code added for a test environment makes its way into production.
