CVE-2018-19790

Pending analysis
Type:
CWE-601 URL Redirection to Untrusted Site ('Open Redirect')
Publication date:
18/12/2018
Last modified:

Description

An open redirect was discovered in Symfony 2.7.x before 2.7.50, 2.8.x before 2.8.49, 3.x before 3.4.20, 4.0.x before 4.0.15, 4.1.x before 4.1.9 and 4.2.x before 4.2.1. By using backslashes in the `_failure_path` input field of login forms, an attacker can work around the redirection target restrictions and effectively redirect the user to any domain after login.
