The vulnerability identified as CVE-2019-17232 resides within the ultimate-faqs WordPress plugin version 1.8.24 and earlier, specifically in the Functions/EWD_UFAQ_Import.php component. This flaw represents a critical security weakness that allows any unauthenticated user to perform options import operations without requiring valid credentials or administrative privileges. The vulnerability stems from insufficient access control mechanisms within the plugin's import functionality, creating an unauthorized entry point that could be exploited by malicious actors to manipulate the plugin's configuration settings.
The technical nature of this vulnerability aligns with CWE-284, which addresses improper access control issues in software systems. The flaw exists because the import function lacks proper authentication checks and authorization validations that should normally be required before allowing modification of plugin options. Attackers can leverage this weakness to inject malicious configuration data, potentially altering how the FAQ plugin operates or redirecting user interactions to malicious endpoints. The unauthenticated nature of the exploit means that no prior login credentials or administrative access are required to trigger the vulnerable code path.
From an operational impact perspective, this vulnerability creates significant risks for WordPress sites utilizing the ultimate-faqs plugin. An attacker could potentially modify FAQ display settings, inject malicious content into FAQ entries, or alter plugin behavior to redirect users to phishing sites. The implications extend beyond simple data manipulation as the compromised plugin could serve as a foothold for further attacks on the WordPress installation. This vulnerability particularly affects sites where the FAQ plugin is used for critical information dissemination or customer support functions, as malicious modifications could mislead users or compromise the integrity of the site's information.
The attack surface for this vulnerability is particularly concerning given that it affects a widely used plugin with minimal authentication requirements. The ATT&CK framework categorizes this type of vulnerability under privilege escalation and persistence tactics, as attackers could use the import functionality to establish backdoors or maintain access to compromised systems. Mitigation strategies should include immediate plugin updates to versions that address this access control flaw, implementation of web application firewalls to monitor and block suspicious import requests, and regular security audits of plugin configurations. Additionally, administrators should consider restricting access to plugin management functions through network-level controls and ensure that only authorized personnel have the ability to modify plugin settings. The vulnerability underscores the importance of proper input validation and authentication checks in web applications, particularly those handling user data or configuration settings that could impact system behavior.
