How the Exploit Works
The SSRF vulnerability in Pik Online allows an attacker to induce the server to make HTTP requests to an arbitrary destination, including potentially to other internal resources within the network. This could be leveraged to perform actions not intended by the server or to gain unauthorized access to data.
Conceptual Example Code
A conceptual example of how this vulnerability might be exploited is as follows:
POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "url": "http://internal-resource" }In this example, the attacker places the URL of an internal resource in the “url” field of the JSON payload. When the server receives this request, it may inadvertently retrieve information from the internal resource and return it in the response to the attacker, leading to potential data leakage.
Mitigation Guidance
The recommended mitigation action for CVE-2025-5260 is to apply the vendor patch for Pik Online. Organizations should upgrade their Pik Online to version 3.1.5 or later to avoid being vulnerable to this attack. As a temporary mitigation, organizations could use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to monitor and potentially block malicious requests. However, it is crucial to note that these are temporary measures and do not resolve the root vulnerability. Therefore, applying the vendor patch remains the most effective long-term solution.
