CVE-2023-24366

Vulnerability

An arbitrary file download vulnerability exists in rConfig v6.8.0, specifically in the file download functionality. The application fails to properly validate user-supplied input, allowing an attacker to specify arbitrary file paths. This issue is present in the default installation and does not require any special configuration to be exploitable. [1]

Exploitation

An attacker with network access to the rConfig web interface can exploit this vulnerability by sending a crafted HTTP request containing path traversal sequences (e.g., ../) to the vulnerable endpoint. No authentication is required. The attacker can then download any file readable by the web server process, such as configuration files, database credentials, or system files. [1]

Impact

Successful exploitation leads to unauthorized disclosure of sensitive information. An attacker can retrieve files containing database credentials, application secrets, or other confidential data, potentially enabling further compromise of the system. The impact is limited to confidentiality; no code execution or data modification is achieved through this vulnerability alone.

Mitigation

As of the publication date (2023-03-27), no official patch or fixed version has been released by the vendor. Users are advised to restrict network access to the rConfig web interface, implement web application firewall rules to block path traversal attempts, or consider migrating to an alternative solution if the software is no longer maintained. The available reference does not provide a workaround or patch details. [1]
