CakePHP Authentication is an authentication plugin for CakePHP that can also be used in PSR-7 based applications. Prior to 2.11.1, 3.3.6, and 4.1.1, the getLoginRedirect() method contains a weakness to backslash bypasses that allows redirect targets with attacker-controlled hostnames through the redirect query string parameter. This issue is fixed in versions 2.11.1, 3.3.6, and 4.1.1.
AI Analysis
Technical Summary
The CakePHP Authentication plugin's getLoginRedirect() method prior to versions 2.11.1, 3.3.6, and 4.1.1 contains a URL redirection vulnerability (CWE-601). This vulnerability allows an attacker to craft redirect URLs with attacker-controlled hostnames by exploiting backslash bypasses in the redirect query string parameter. This can lead to users being redirected to untrusted sites. The vulnerability is fixed in the specified versions.
Potential Impact
An attacker can exploit this vulnerability to redirect users to malicious external websites by manipulating the redirect query string parameter. This could facilitate phishing attacks or other social engineering tactics by misleading users into trusting malicious destinations. The CVSS 4.0 base score is 5.1 (medium severity), indicating a moderate risk without requiring privileges or user interaction beyond clicking a link.
Mitigation Recommendations
Upgrade the CakePHP Authentication plugin to version 2.11.1, 3.3.6, or 4.1.1 or later, where this vulnerability has been fixed. No other mitigation steps are indicated in the advisory. Patch status is confirmed by the vendor advisory stating the issue is fixed in these versions.
