Arbitrary File Read Vulnerability in savane.git (index.php) with POC

Vulnerability Overview The provided screenshot displays a file named within the Git repository. The file contains code related to file download and access control. The specific vulnerability lies in the lack of proper validation of the filename during file downloads, which may lead to an Arbitrary File Read vulnerability. Impact Scope Impact Scope: Any user who can access this file may exploit this vulnerability to read arbitrary files on the server. Potential Risk: An attacker can construct specific URL parameters to read sensitive files on the server, such as configuration files, source code, etc. Remediation 1. Validate File Names: Perform strict validation on the file name before downloading, ensuring the file name is legal and within the allowed directory range. 2. Restrict Access: Implement access control for file access, ensuring that only authorized users can access specific files. 3. Use a Whitelist: Establish a whitelist of allowed file names for download; only files in the whitelist can be downloaded. POC Code The following is an example of POC code that could be used to exploit this vulnerability: Full Code Block Below is the key code block in related to file download: The above code block demonstrates the specific implementation of file download and access control. The insufficient validation of file names may lead to an Arbitrary File Read vulnerability.
