CyberRota Analysis
AI-GeneratedThe vulnerability allows attackers to exploit the URL redirection feature in the Phoenix LiveView framework, enabling them to redirect users to untrusted sites through manipulated URL parameters. This can lead to phishing attacks or other malicious activities, as the framework fails to properly validate certain ASCII characters, allowing crafted URLs to bypass security checks. Organizations using affected versions of Phoenix LiveView should prioritize patching to mitigate potential risks associated with this vulnerability.

Original NVD Description
URL Redirection to Untrusted Site ('Open Redirect') vulnerability in phoenixframework phoenix_live_view allows an attacker to send a victim's browser to an origin of the attacker's choosing via a :to value containing ASCII tab, LF or CR. redirect/2 validates :to through the private validate_local_url!/2 in lib/phoenix_live_view.ex, which is intended to guarantee the target is a path within the application. It rejects a leading // and any backslash, but not ASCII tab, LF or CR. Browsers strip those three characters before parsing a URL, so a value such as /<TAB>/example.com passes validation as a path and is then resolved as the scheme-relative URL //example.com. The live navigation functions share the guard but are not affected, because the client expands their target against the current origin. push_patch/2 is also affected before 0.7.0, which is when that expansion was added. This issue affects phoenix_live_view: from 0.5.0 before 1.0.19, from 1.1.0-rc.0 before 1.1.33, and from 1.2.0-rc.0 before 1.2.9.
