Overview
The cybersecurity landscape is a perpetual battlefield, with new vulnerabilities emerging regularly. One such high-severity vulnerability, tagged as CVE-2024-32832, has been detected in Hamid Alinia’s “Login with phone number” software. This vulnerability arises from a missing authorization check, which, if exploited, could lead to complete system compromise or data leakage. This vulnerability is particularly important to address as it affects the security of user login processes, a critical component in maintaining the overall security of any system.

How the Exploit Works
The exploit takes advantage of the missing authorization logic in the “Login with phone number” feature. An attacker can send a specially crafted request to the application, bypassing the authorization process. This allows unauthorized access to the system without requiring the correct credentials. The attacker then gains the same access or privileges as a legitimate user, leading to the potential for system compromise or data leakage.
Conceptual Example Code
Here’s a conceptual representation of how the vulnerability might be exploited. This example assumes the attacker is using an HTTP POST request to the server.
POST /login HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"phone_number": "1234567890",
"bypass_auth": "True"
}In this example, the attacker uses the `bypass_auth` parameter in the request, which is not correctly checked for authorization by the server. As a result, the server grants access to the attacker without validating the phone number or the need for a password.
Mitigation Guidance
As a mitigation measure, users are advised to apply the vendor patch as soon as it becomes available. In the meantime, users can employ a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation strategy. These systems can detect and block abnormal traffic patterns or potentially malicious requests, providing some relief until the patch is released and applied.
