linjiashop | <=0.9 How the Exploit Works

The CVE-2025-52101 vulnerability lies in the incorrect access control of the linjiashop software. In detail, when using the default-generated JWT (JSON Web Token) authentication, attackers can bypass this authentication layer. This bypass allows attackers to retrieve the encrypted “password” and “salt” information. With this data in hand, attackers can then use brute-force cracking techniques to decipher the password, gaining unauthorized access to the system.

Conceptual Example Code

Here’s a conceptual example of how this vulnerability might be exploited using an HTTP request:

GET /api/userinfo HTTP/1.1
Host: target.example.com
Authorization: Bearer default-generated-jwt

In this example, an attacker uses a default-generated JWT in the Authorization header to bypass authentication and retrieve user information, which includes encrypted passwords and salts.

Mitigation and Patch Info

To mitigate this vulnerability, it is recommended to apply the vendor patch as soon as it becomes available. Until then, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) could be used as a temporary mitigation method to monitor and block suspicious activities. Be vigilant about monitoring your systems for any signs of unauthorized access or unusual activity.
In conclusion, CVE-2025-52101 is a critical vulnerability that highlights the importance of robust security practices in the realm of software development and the cybersecurity landscape. Businesses must remain vigilant and proactive in applying patches and updates to ensure the security of their online platforms.
