Official description
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 underlying weakness: Allocation of Resources Without Limits or Throttling
The product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated.
How developers prevent this class of flaw
- Clearly specify the minimum and maximum expectations for capabilities, and dictate which behaviors are acceptable when resource allocation reaches limits.
- Limit the amount of resources that are accessible to unprivileged users. Set per-user limits for resources. Allow the system administrator to define these limits. Be careful to avoid CWE-410.
- For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
