How the Exploit Works

The CVE-2025-45609 vulnerability lies in the doFilter function of the kob latest v1.0.0-SNAPSHOT. Incorrect access control in this function allows an attacker to craft a payload that can bypass the existing security measures. Consequently, the attacker could gain unauthorized access to sensitive data or potentially compromise the system.

Conceptual Example Code

The following is a conceptual example of how an HTTP request exploiting this vulnerability might look like:

POST /doFilter HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "crafted_payload": "..." }

In this example, the “crafted_payload” is designed to bypass the doFilter function’s access control, allowing the attacker to gain unauthorized access to sensitive data.

Mitigation Guidance

The most effective way to address this vulnerability is by applying the vendor-supplied patch. If this is not immediately feasible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure. It is also recommended to keep a close eye on network traffic for any unusual activity or attempted exploits.
