An unauthenticated Denial of Service (DoS) vulnerability was identified in ChuanhuChatGPT version 20240918, which could be exploited by sending large data payloads using a multipart boundary. Although a patch was applied for CVE-2024-7807, the issue can still be exploited by sending data in groups with 10 characters in a line, with multiple lines. This can cause the system to continuously process these characters, resulting in prolonged unavailability of the service. The exploitation now requires low privilege if authentication is enabled due to a version upgrade in Gradio.
The product does not properly control the allocation and maintenance of a limited resource.

Mitigation of resource exhaustion attacks requires that the target system either:
The first of these solutions is an issue in itself though, since it may allow attackers to prevent the use of the system by a particular valid user. If the attacker impersonates the valid user, they may be able to prevent the user from accessing the server in question.
The second solution is simply difficult to effectively institute – and even when properly done, it does not provide a full solution. It simply makes the attack require more resources on the part of the attacker.
