This cross-site request forgery vulnerability exists within the Redirect wordpress to welcome or landing page plugin version range from n/a through 2.0, representing a critical security flaw that enables attackers to execute stored cross-site scripting attacks. The vulnerability stems from insufficient validation of user-supplied input within the plugin's csrf protection mechanisms, allowing malicious actors to craft malicious requests that bypass the standard security controls. The flaw specifically manifests when the plugin processes redirect configurations or user input parameters without proper sanitization, creating an attack surface where crafted payloads can be permanently stored and subsequently executed in the context of authenticated users' browsers. This vulnerability aligns with CWE-352, which categorizes cross-site request forgery flaws, and demonstrates how inadequate csrf protection can lead to more severe consequences including persistent stored xss exploitation. The attack vector involves an attacker manipulating the plugin's configuration interface or api endpoints to inject malicious javascript payloads that get stored within the application's database or configuration files.
The operational impact of this vulnerability extends beyond simple csrf exploitation, as it creates a persistent threat that can affect all users who interact with the compromised wordpress site. When authenticated administrators or users visit pages that trigger the execution of stored malicious code, the xss payload executes in their browser context, potentially leading to session hijacking, credential theft, or redirection to malicious sites. The stored nature of this xss vulnerability means that once the malicious payload is injected, it remains active until manually removed from the plugin configuration or the affected database entries. This persistence factor significantly amplifies the threat surface and makes the vulnerability particularly dangerous in environments where multiple users interact with the compromised system. The vulnerability affects all versions within the specified range, indicating that organizations running any version from the initial release through 2.0 are potentially at risk, regardless of their security measures. The flaw demonstrates how csrf protection mechanisms that fail to properly validate or sanitize user input can create cascading security issues that extend far beyond the original attack surface.
Mitigation strategies for this vulnerability require immediate attention from system administrators and security teams. The primary recommendation involves upgrading to the latest available version of the plugin where the csrf protection has been properly implemented and validated. Organizations should also implement additional security controls such as content security policies to limit the execution of malicious scripts, input validation at multiple layers including application and database levels, and regular security scanning of plugin configurations. Network-level protections including web application firewalls can help detect and block suspicious csrf requests that attempt to exploit this vulnerability. Security teams should conduct comprehensive audits of all installed plugins to identify similar csrf flaws and ensure that proper token validation mechanisms are implemented across all user-facing interfaces. The vulnerability also highlights the importance of proper security testing during plugin development cycles, particularly around csrf protection implementation and input sanitization procedures. Organizations should consider implementing automated patch management systems to ensure rapid deployment of security updates and maintain detailed inventory of all third-party components to enable quick identification of affected systems. This vulnerability serves as a reminder of the critical importance of validating all user-supplied input and implementing robust csrf protection mechanisms to prevent attackers from exploiting seemingly minor security gaps that can lead to severe consequences including persistent stored cross-site scripting attacks.
