CVE-2025-2636 Scanner

The InstaWP Connect plugin is designed to facilitate 1-click staging and migration of WordPress websites. It is used by web administrators and developers to efficiently replicate website environments for testing and migration purposes. The plugin’s core function is to simplify the deployment and management of WordPress sites, making it indispensable for many WordPress users. It is often employed in development environments to maintain seamless updates and experiment with site changes. By creating an identical staging site, users can test new features without affecting the live environment. This significantly mitigates risks associated with updates or new installations on WordPress platforms.

The identified vulnerability in InstaWP Connect is a Local File Inclusion (LFI) weakness. It allows unauthorized attackers to include and execute arbitrary files on the server. This could result in the execution of any PHP code contained within those files, posing significant security risks. Such vulnerabilities are critical as they could permit extensive unauthorized access and manipulation of server resources. LFI allows attackers to escalate from a minor misconfiguration to full server exploitation, potentially leading to data breaches. The vulnerability is particularly concerning due to the ease with which it can be exploited without authenticated access.

The technical specifics of the vulnerability involve exploiting the 'instawp-database-manager' parameter. Unauthorized users can manipulate this parameter to execute malicious PHP scripts by referencing system files outside of the plugin’s permitted directory. The vulnerability affects all versions up to and including 0.1.0.85. By manipulating the file parameters, attackers can induce the server to process arbitrary files. This significantly increases the risk of full-scale server compromise, particularly when sensitive configuration files are accessed or modified.

If exploited, this vulnerability could lead to several severe outcomes. An attacker could execute malicious code leading to complete server compromise. They could read sensitive configuration files, leading to information disclosure. Additionally, such exploitation could result in backend server functionality manipulation, impacting overall site integrity. In worse scenarios, it could provide a foothold for attackers to gain further access to an organization’s network, escalating to broader data breaches. Finally, sites using vulnerable versions might be susceptible to downtime or defacement, impacting business operation and reputation.
