Vulnerability from csaf_redhat - Published: 2015-10-08 12:11 - Updated: 2026-06-28 12:26

Summary

Red Hat Security Advisory: python-django security update

Severity

Moderate

Notes

Topic: Updated python-django packages that fix one security issue are now available for Red Hat Enterprise Linux OpenStack Platform 7.0. Red Hat Product Security has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

Details: Django is a high-level Python Web framework that encourages rapid development and a clean, pragmatic design. It focuses on automating as much as possible and adhering to the DRY (Don't Repeat Yourself) principle. It was found that Django incorrectly handled the session store. A session could be created by anonymously accessing the django.contrib.auth.views.logout view if it was not decorated correctly with django.contrib.auth.decorators.login_required. A remote attacker could use this flaw to fill up the session store or cause other users' session records to be evicted by requesting a large number of new sessions. (CVE-2015-5963) Red Hat would like to thank the upstream Django project for reporting this issue. All python-django users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.

Related by attack behaviour

Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
