2) Resource exhaustion

EUVDB-ID: #VU11476

Risk: Low

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-7537

CWE-ID: CWE-400 - Resource exhaustion

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists in the django.utils.html.urlize() function due to it was extremely slow to evaluate certain inputs due to catastrophic backtracking vulnerabilities in two regular expressions. The urlize() function is used to implement the urlize and urlizetrunc template filters, which were thus vulnerable. A remote attacker can cause the service to crash.

Mitigation

CWE-ID: CWE-601 - URL Redirection to Untrusted Site ('Open Redirect')

Exploit availability: No

Description

The vulnerability allows a remote unauthenticated attacker to redirect the target user to external websites.

The weakness exists on systems with django.middleware.common.CommonMiddleware and the APPEND_SLASH setting enabled and with a project that has a URL pattern that accepts any path ending in a slash due to open redirect. A remote attacker can use a specially crafted image link, trick the victim into opening it and redirect users to malicious website
