CVE-2024-27564 Scanner

ChatGPT is a customized version of ChatGPT, used primarily in specialized applications requiring advanced language model capabilities. It is commonly implemented in customer support, content creation, and other professional settings where AI-driven automation is beneficial. This software is deployed on web servers and integrates with various online services to enhance user interaction. It is maintained by development teams familiar with its codebase and intended functionality. ChatGPT is tailored to meet specific business needs, ensuring efficient and accurate performance.

The detected vulnerability is a Server-Side Request Forgery (SSRF) in the pictureproxy.php component of ChatGPT. This flaw allows attackers to manipulate the server into making unauthorized requests. Exploiting this vulnerability can lead to exposure of sensitive information and unauthorized actions on behalf of the server. The SSRF vulnerability can be triggered through crafted URL injections in the url parameter.

The SSRF vulnerability is located in the pictureproxy.php file, specifically affecting the url parameter. When an attacker inputs a maliciously crafted URL, the application processes the request and retrieves the resource specified by the attacker. This can result in the server making internal network requests or accessing restricted resources. The vulnerability can be verified by checking the response status code, headers, and response body for indications of unauthorized requests. It also allows attackers to manipulate the DNS resolution process, further exploiting the system's internal network.

Exploiting this SSRF vulnerability can have severe consequences, including unauthorized access to internal systems, data exfiltration, and exposure of sensitive files such as /etc/passwd. It can also enable attackers to bypass network restrictions and interact with services that are otherwise protected. This can lead to significant security breaches, loss of confidential information, and potential system compromise. The attacker can also use this vulnerability to conduct further attacks, such as escalating privileges or conducting lateral movement within the network.
