CVE-2023-38877: Economizzer host header injection vulnerability

A host header injection vulnerability exists in gugoan's Economizzer v.0.9-beta1 and commit 3730880 (April 2023). By sending a specially crafted host header in the reset password request, it is possible to send password reset links to users which, once clicked, lead to an attacker-controlled server and thus leak the password reset token. This allows an attacker to reset other users' passwords.

Root Cause Analysis

The vulnerability stems from improper validation of the Host header when constructing password reset links. In Yii applications, password reset functionality typically involves: 1) A controller action handling the reset request (e.g., actionRequestPasswordReset), and 2) A model method (e.g., sendPasswordResetEmail) that generates the reset URL. The vulnerability occurs when these functions use Yii's request->getHostInfo() or similar methods that trust the Host header without validation. This matches the CWE-94 pattern where untrusted input (Host header) directly controls URL generation. The high confidence comes from the vulnerability's nature and typical Yii architecture patterns, even without direct access to the exact code diff.
