CVE-2024-9146

Vulnerability

Overview

The CSS JS Files plugin for WordPress (versions up to and including 1.5.0) contains a path traversal vulnerability. The plugin fails to properly restrict file paths, allowing an attacker to traverse directories outside the intended scope. This is classified as an Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') issue [1].

Exploitation

An attacker can exploit this vulnerability without authentication by sending specially crafted requests to the plugin. The attack surface is the plugin's file-handling functionality, which does not validate user-supplied path inputs. No special network position is required; the attacker only needs to be able to send HTTP requests to the WordPress site [1].

Impact

Successful exploitation enables an attacker to read arbitrary files from the server's filesystem. This includes sensitive files such as configuration files, database credentials, or other application data. The attacker can also enumerate the existence of files and directories, which may aid in further attacks [1].

Mitigation

The vulnerability has been addressed in a patched version. Users are strongly advised to update the CSS JS Files plugin to the latest available version. If immediate updating is not possible, it is recommended to contact the hosting provider or a web developer for assistance. This vulnerability is known to be used in mass-exploit campaigns, making timely patching critical [1].
