Arbitrary File Path Injection Vulnerability in Chat History Upload

CVE-2024-4321

What is CVE-2024-4321?

CVE-2024-4321 refers to a significant security vulnerability found in the gaizhenbiao/chuanhuchatgpt application, which is primarily utilized for managing chat history uploads. This vulnerability stems from an inadequate validation of user inputs, specifically within the file path handling feature. As a result, it poses a serious risk to organizations using this application, as attackers could potentially exploit this flaw to read sensitive server files, leading to unauthorized access to confidential information and operational disruption.

Technical Details

The vulnerability manifests as a Local File Inclusion (LFI) flaw, which originates from improper handling of the 'name' parameter during the chat history upload process. Attackers can intercept and manipulate requests to specify arbitrary file paths, facilitating unauthorized access to sensitive files stored on the server. Specifically, this issue affects version 20240310 of the application, enabling potential exploitation through crafted upload requests that bypass normal input restrictions.

Potential Impact of CVE-2024-4321

1. Information Leakage: The most critical impact of this vulnerability is the potential exposure of sensitive files, including API keys and user data stored on the server. This could greatly compromise the confidentiality of critical business operations.

2. Infrastructure Compromise: By leveraging this vulnerability, an attacker could gain insights into the overall architecture and configuration of the internal systems, thereby facilitating further attacks on the network and its assets.

3. Operational Disruption: The breach of sensitive information can lead to operational disruptions, including the potential for service outages or a loss of trust among users and clients, which could negatively impact the organization's reputation and bottom line.
