The CVE-2024-27967 vulnerability represents a critical cross-site request forgery flaw within the DSGVO All in one for WP plugin, a widely used WordPress solution for managing data protection compliance under the General Data Protection Regulation. This vulnerability exists in versions ranging from the initial release through version 4.3, creating a persistent security risk for WordPress sites that rely on this plugin for GDPR compliance management. The flaw stems from inadequate validation of HTTP request origins and lack of proper anti-CSRF token implementation within the plugin's administrative interfaces. Attackers can exploit this weakness by crafting malicious requests that appear to originate from legitimate administrative sessions, potentially enabling unauthorized actions within the WordPress administration panel. The vulnerability specifically impacts the plugin's ability to distinguish between genuine user requests and maliciously forged ones, undermining the fundamental security controls that protect administrative functions.
The technical implementation of this CSRF vulnerability manifests through the absence of anti-CSRF tokens in critical administrative endpoints within the plugin's codebase. This weakness allows attackers to perform unauthorized administrative actions without proper authentication, as the plugin fails to verify the authenticity of requests originating from the legitimate user's browser session. The vulnerability operates by leveraging the browser's automatic inclusion of cookies for requests to the same origin, enabling attackers to execute malicious requests on behalf of authenticated administrators. This flaw directly maps to CWE-352, which categorizes cross-site request forgery vulnerabilities as a serious threat to web application security, particularly when affecting administrative functions. The vulnerability's impact is amplified because the plugin's administrative interface handles sensitive data protection configurations, making successful exploitation potentially devastating for site security and compliance status.
The operational impact of this CSRF vulnerability extends beyond simple unauthorized access, as it can lead to complete compromise of the WordPress site's data protection mechanisms and administrative control. An attacker who successfully exploits this vulnerability could modify privacy settings, alter cookie consent configurations, disable security features, or potentially gain access to sensitive user data stored within the plugin's management interface. This risk is particularly severe for organizations operating under GDPR compliance requirements, as unauthorized changes to privacy management settings could result in regulatory violations and significant financial penalties. The vulnerability affects the plugin's core functionality for managing user consent, cookie banners, and data processing agreements, potentially leaving sites vulnerable to data breaches and non-compliance with data protection regulations. The attack surface is further expanded because WordPress administrators often have elevated privileges, making successful exploitation particularly damaging to overall site security posture.
Mitigation strategies for this CSRF vulnerability should prioritize immediate plugin updates to versions that address the identified flaw, as the vendor has likely released patches to implement proper anti-CSRF token validation. Organizations should also implement additional security measures such as network-level protections, including web application firewalls that can detect and block suspicious request patterns, and regular monitoring of administrative access logs for anomalous activity. Security teams should conduct comprehensive audits of all installed WordPress plugins to identify similar vulnerabilities and ensure proper CSRF protection mechanisms are in place across the entire web application stack. The implementation of Content Security Policy headers and proper session management practices can further reduce the risk of exploitation, while regular security assessments should be conducted to identify potential CSRF vulnerabilities in custom-developed web applications. This vulnerability underscores the importance of maintaining up-to-date security practices and the critical need for robust input validation and authentication mechanisms in web applications. The ATT&CK framework categorizes this type of vulnerability under T1566, which covers credential access through social engineering and web application attacks, highlighting the need for comprehensive defensive strategies that address both technical and human factors in security.
