CVE-2025-5394 Scanner

Alone Theme, specifically designed for charity, multipurpose, and non-profit organizations, is a popular WordPress theme. It is used by many content creators and website administrators to build and manage their online presence with ease, offering numerous customization options and ready-to-use templates. Alone Theme enhances the functionality of WordPress by providing a user-friendly interface and multiple features tailored for the non-profit sector. It simplifies the process of creating donation pages, event management, and content marketing. The theme is widely adopted by those looking to create responsive and visually appealing websites without extensive coding knowledge. Its integration with WordPress makes it a versatile tool for building impactful non-profit websites.

The vulnerability detected in Alone Theme is an unrestricted file upload flaw. This security issue allows attackers to upload arbitrary files to the server, bypassing authentication and authorization checks. In particular, the vulnerability arises from missing capability checks on a specific function within the theme, potentially enabling remote code execution. This can pose a serious threat by allowing attackers to manipulate server files or drop malicious scripts. If exploited, it could lead to unauthorized access to sensitive data or complete control over the affected system. The vulnerability is critically severe and needs immediate remediation to prevent potential exploitation.

Technically, the vulnerability lies in the absence of proper authentication checks in the alone_import_pack_install_plugin() function. This function permits the insecure uploading of plugins from remote URLs, enabling the possibility of uploading zip files containing malicious code. Attackers can exploit this flaw by sending specifically crafted requests that include web shells or other malicious payloads packaged as WordPress plugins. The exploit occurs over the HTTP protocol when requests to wp-admin/admin-ajax.php do not validate the user's permissions. As a result, this can lead to the execution of arbitrary code on the server hosting the WordPress application.

If this vulnerability is exploited, it can result in severe consequences such as remote code execution, allowing attackers to gain complete control over the WordPress environment. Unauthorized users might upload malicious plugins, compromising the integrity and security of the website. The attack could lead to a web shell being installed, facilitating further exploitation or data theft. Additionally, the site's reputation could be damaged due to the unauthorized content modifications or distribution of malware. Mitigating this risk is crucial to maintaining the security and reliability of the affected systems.
