CVE-2018-7536: An issue was discovered in Django 2.0 before 2.0.3, 1.11 before 1.11.11, and 1.8 before 1.8.19.

MediumCVSS 5.3 · v3.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 4.5% (FIRST EPSS); higher than 91.7% 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. No special conditions are required; it is repeatable.
  • Fixed version: py-django (Alpine:v3.10) 1.11.11-r0; py3-django (Alpine:v3.11) 1.11.11-r0; py-django (Alpine:v3.4) 1.8.19-r0.

Low priority for now. Upgrade to py-django (Alpine:v3.10) 1.11.11-r0; py3-django (Alpine:v3.11) 1.11.11-r0; py-django (Alpine:v3.4) 1.8.19-r0 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

An issue was discovered in Django 2.0 before 2.0.3, 1.11 before 1.11.11, and 1.8 before 1.8.19. The django.utils.html.urlize() function was extremely slow to evaluate certain inputs due to catastrophic backtracking vulnerabilities in two regular expressions (only one regular expression for Django 1.8.x). The urlize() function is used to implement the urlize and urlizetrunc template filters, which were thus vulnerable.
