CVE-2024-10410: Critical Vulnerability Found in SourceCodester Online Hotel Reservation System 1. Allows Unrestricted File Upload

A critical vulnerability, identified as CVE-2024-10410, has been discovered in SourceCodester Online Hotel Reservation System 1.. This vulnerability has been classified as critical due to its potential to allow an attacker to perform unrestricted file uploads. The function "upload" within the file /admin/mod_room/controller.php?action=add is specifically affected, and the manipulation of the "image" argument is what leads to the vulnerability. This attack can be performed remotely, posing a serious risk to organizations utilizing this system. The exploit has been disclosed to the public, and it is possible that it may be used maliciously in the near future.

Code Snippet

The vulnerability can be observed in the following code snippet which is found within the /admin/mod_room/controller.php?action=add file:

if (!empty($_FILES['room_image']['tmp_name'])) {
    $image = addslashes(file_get_contents($_FILES['room_image']['tmp_name']));
} else {
    $image = "";
}

Exploit Details

The critical vulnerability is essentially due to a lack of proper validation of user-uploaded files. An attacker, by manipulating the "image" argument, can bypass any potential safeguards put in place to protect against malicious file uploads. Consequently, an attacker can upload unrestricted files, potentially executing malicious code or allowing unauthorized access to sensitive information.

The following steps detail the exploitation process

1. The attacker targets the vulnerable function, which is responsible for adding new room images to the system.

2. The attacker manipulates the "image" argument, injecting malicious payloads into the system through the unrestricted file upload.

3. The system processes the uploaded file without properly validating its content, unwittingly executing the malicious payload.

4. The attacker gains unrestricted access to the system, allowing them to potentially perform various malicious activities, such as manipulation of sensitive data, and unauthorized control over the system.

Mitigation Measures

Organizations using the SourceCodester Online Hotel Reservation System 1. are strongly urged to apply a suitable patch or update their system to protect against this critical vulnerability. In the meantime, the following steps can be taken to limit the potential impact of this vulnerability:

1. Ensure that proper file validation measures are in place to check for valid file formats and sizes before allowing any user-uploaded files into the system.

2. Implement file-content validation, such as signature scanning, to further enhance the protection against potentially malicious files.

3. Limit the permissions of users who can upload files, essentially narrowing the threat vector and preventing a potential attacker from exploiting this vulnerability.

4. Regularly monitor the system for any unauthorized or suspicious activities and take immediate action to mitigate any risks that are discovered.
