CVE-2024-7226: Medicine Tracker System CSRF Vulnerability

CVE-2024-7226 Overview

CVE-2024-7226 is a Cross-Site Request Forgery (CSRF) vulnerability [CWE-352] affecting SourceCodester Medicine Tracker System 1.0, developed by oretnom23. The flaw resides in the Password Change Handler component, specifically in the /classes/Users.php?f=save_user endpoint. Attackers can craft malicious web requests that, when triggered by an authenticated user's browser, perform unauthorized password change operations without the user's consent. The exploit has been publicly disclosed and tracked as VulDB identifier VDB-272806. The vulnerability is remotely exploitable over the network and requires no authentication from the attacker, though it depends on victim interaction with a malicious page.

Critical Impact
An unauthenticated remote attacker can hijack an authenticated user's session context to change account passwords, leading to account takeover of Medicine Tracker System users.

Technical Details for CVE-2024-7226

Vulnerability Analysis

The vulnerability stems from missing anti-CSRF protections on the save_user action handled by /classes/Users.php. The application processes password change requests based solely on the session cookie, without validating a synchronizer token, double-submit cookie, or origin/referer header. Because browsers automatically attach session cookies to cross-origin requests, an attacker-hosted page can submit a forged form or fetch request that mutates user account state.

The issue is classified under [CWE-352] (Cross-Site Request Forgery). According to the EPSS forecast, the probability of exploitation in the wild is 0.379% with a percentile of 29.578.

Root Cause

The root cause is the absence of request authenticity validation on a state-changing endpoint. The save_user handler accepts POST parameters that update user credentials but does not verify that the request originated from a legitimate, user-initiated action within the application. No CSRF token is generated, embedded in forms, or validated server-side.

Attack Vector

An attacker hosts a malicious HTML page containing an auto-submitting form that targets the vulnerable /classes/Users.php?f=save_user endpoint with attacker-controlled credential parameters. When an authenticated administrator or user visits the page, the browser forwards the active session cookie alongside the forged request, and the server processes the password change as if it were legitimate. Successful exploitation results in account takeover. Public proof-of-concept details are available in the GitHub CSRF Vulnerability Report and the VulDB entry #272806.

Detection Methods for CVE-2024-7226

Indicators of Compromise

Unexpected password change events in application logs targeting /classes/Users.php?f=save_user
HTTP POST requests to save_user containing Referer headers pointing to external or unknown domains
User reports of being unable to log in shortly after browsing external sites
Successive save_user requests for the same account from disparate IP addresses

Detection Strategies

Inspect web server access logs for POST requests to /classes/Users.php?f=save_user with missing or external Origin and Referer headers
Correlate password change events with the absence of a preceding GET to the user profile page in the same session
Deploy a web application firewall rule that flags state-changing POSTs lacking a valid same-origin referer

Monitoring Recommendations

Centralize PHP application and web server logs for the Medicine Tracker System and alert on password change frequency anomalies
Monitor authentication audit trails for password modifications not preceded by a current-password validation step
Track outbound user-agent patterns and session reuse across geographically inconsistent IPs

How to Mitigate CVE-2024-7226

Immediate Actions Required

Restrict access to the Medicine Tracker System to trusted internal networks or place it behind a VPN until a fix is applied
Force password resets for all existing users and invalidate active sessions
Deploy a web application firewall rule that rejects POSTs to /classes/Users.php?f=save_user lacking a same-origin Referer or Origin header

Patch Information

No official vendor patch is referenced in the NVD record for CVE-2024-7226. Administrators should monitor the VulDB advisory and the upstream SourceCodester project for updates. In the absence of a vendor fix, application owners should modify /classes/Users.php to require a per-session CSRF token validated server-side on every state-changing action, and require the user's current password before accepting any password change.

Workarounds

Implement a synchronizer CSRF token in all forms that invoke save_user and validate it server-side before processing
Set application session cookies with SameSite=Strict (or at minimum SameSite=Lax) to limit cross-origin cookie transmission
Enforce re-authentication by requiring the current password as a parameter to the password change handler
Add server-side Origin and Referer header validation that rejects requests from unexpected domains

bash

# Example PHP session hardening to reduce CSRF exposure
# Place in application bootstrap before session_start()
session_set_cookie_params([
    'lifetime' => 0,
    'path'     => '/',
    'secure'   => true,
    'httponly' => true,
    'samesite' => 'Strict'
]);
session_start();
