WordPress Plugin OPS Old Post Spinner Local File Inclusion Scanner

WordPress Plugin OPS Old Post Spinner is a tool used by website owners to manage and update the content of their blogs efficiently. Primarily used within the WordPress ecosystem, this plugin helps automate the creation of new versions of old posts. Its features are especially useful for bloggers who want to keep their content fresh and relevant by periodically updating their older posts. Due to its integration with WordPress, it is developed in PHP and often utilized on sites hosted on MySQL servers. The plugin is popular because it provides seamless post updates without needing significant manual intervention.

The Local File Inclusion (LFI) vulnerability allows attackers to include files from the server within the execution context. Attackers exploit this vulnerability by tricking the server into including unintended files, potentially revealing sensitive data or allowing the execution of arbitrary code. The vulnerability is often introduced when input data is not correctly sanitized, allowing the inclusion of file paths. LFI is a critical issue because it jeopardizes data confidentiality, integrity, and availability. The vulnerability in the OPS Old Post Spinner arises from the improper handling of the ops_file parameter, allowing path traversal and potentially exposing sensitive server files.

The technical details of this vulnerability revolve around the improper validation and sanitization of the ops_file parameter in the plugin. The vulnerable endpoint can be exploited using a crafted URL to include files from the server. Attackers manipulate the input to traverse directories and potentially access critical files like configuration files. The exploitation relies on the server executing or reading unintended files, leading to exposure of sensitive information. The crafted URL attempting inclusion might look like the parameter in logview.php file with directory traversal techniques employed.

Exploitation of the LFI vulnerability could result in unauthorized data exposure, including passwords, configuration details, or other sensitive information. If the server executes included files, it could lead to further attacks like remote code execution or server compromise. Additionally, attackers could gain insights into server configurations or other plugins' vulnerabilities. The overall server security might be weakened, leading to further exploitation through other vulnerabilities. Database security could also be compromised if sensitive credentials are included, leading to extensive breach consequences.
