How the Exploit Works
The exploit works by allowing an attacker to craft a specific GET request. This request, when processed by Zalo v23.09.01, exposes sensitive user information that should not be accessible. The vulnerability lies in the improper handling of GET requests, leading to unintended access to protected data.
Conceptual Example Code
Here is a conceptual example of how the vulnerability might be exploited using a GET request:
GET /user/data HTTP/1.1
Host: target.example.com
User-Agent: ZaloClient/23.09.01
Accept: application/jsonThis GET request could be used by an attacker to retrieve sensitive user data which should otherwise be inaccessible.
Mitigation
The immediate mitigation is to apply the vendor’s patch. If the patch is not available or cannot be applied immediately, use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary solution to detect and block malicious requests. It is strongly recommended to review and update security policies to prevent future vulnerabilities.
