CVE-2024-33605 - Path Traversal Vulnerability in installed_emanual_list.html due to Improper Processing of Parameters

A recent critical vulnerability, identified as CVE-2024-33605, affecting several products has been discovered. It involves improper processing of some parameters within the installed_emanual_list.html file, leading to a path traversal vulnerability. This vulnerability enables attackers to gain unauthorized access to sensitive data and execute arbitrary code on the targeted system. In this article, we will provide a detailed explanation of the vulnerability, the affected products, and versions, and possible exploits.

Vulnerability Details

The vulnerability stems from the improper processing of some parameters in the installed_emanual_list.html file. This file is responsible for handling user input, but it does not correctly validate and sanitize the input before using it in sensitive operations. Consequently, attackers can exploit this vulnerability by manipulating specific parameters, leading to path traversal.

Sample Code Snippet

In the installed_emanual_list.html, the vulnerable parameter is '__]', which gets processed in the following code block:

filter_1 = request.GET.get('__]')
file_path = os.path.join(INSTALL_DIR, filter_1)
validate_path(file_path)

The request.GET.get() method retrieves user input, and the os.path.join() method concatenates the INSTALL_DIR and filter_1 values. The code does not verify that the user input is safe, which introduces the path traversal vulnerability.

Affected Products and Versions

A comprehensive list of affected products, model numbers, and versions can be found under the [References] section. It is crucial for users to check the listed information to determine if their systems are susceptible to the vulnerability. We encourage users to immediately apply the necessary updates and patches provided by the vendors to mitigate the risk.

Exploit Details

An attacker can exploit this vulnerability by crafting a malicious URL containing path traversal payloads targeting the vulnerable parameter. Here's an example:

http://example.com/installed_emanual_list.html?__]=../../../../../etc/passwd

By visiting this URL, an attacker could retrieve sensitive information such as the /etc/passwd file on a Linux-based system, disclosing user data and allowing further intrusion.

Mitigation

To defend against this vulnerability, it is essential to apply the updates and patches provided by your vendor. Additionally, it is good practice to validate and sanitize all user inputs, enforce least privilege access, maintain regular software updates, and monitor your systems for any signs of intrusion.
