CVE-2024-11806 in Centro de Envios Plugin
Summary
by MITRE • 12/20/2024
The PKT1 Centro de envios plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'success' and 'error' parameters in all versions up to, and including, 1.2.1 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

The CVE-2024-11806 vulnerability affects the PKT1 Centro de envios plugin for WordPress, representing a critical security flaw that exposes users to reflected cross-site scripting attacks. This vulnerability specifically targets versions up to and including 1.2.1, making it particularly concerning for WordPress installations that have not yet updated to newer releases. The flaw stems from inadequate input sanitization and output escaping mechanisms within the plugin's codebase, creating an exploitable entry point for malicious actors seeking to compromise user sessions or execute unauthorized scripts.
The technical implementation of this vulnerability occurs through the 'success' and 'error' parameters within the plugin's functionality, which are processed without proper validation or sanitization. When these parameters contain malicious script code, they are reflected back to users who view the affected pages, allowing attackers to inject arbitrary web scripts that execute in the context of the victim's browser. This type of vulnerability falls under CWE-79, which specifically addresses Cross-Site Scripting flaws in software applications. The reflected nature of this vulnerability means that attackers do not need to store malicious code on the server, but instead rely on tricking users into clicking malicious links that contain the exploit payload.
The operational impact of this vulnerability extends beyond simple script injection, potentially enabling attackers to perform a range of malicious activities including session hijacking, credential theft, or redirection to malicious websites. Since the vulnerability affects an unauthenticated attack vector, any user who clicks on a malicious link containing the exploit can become compromised without requiring any prior authentication or privileged access. This makes the attack surface particularly broad and dangerous in real-world scenarios where users may encounter such links in email communications, social media posts, or compromised websites. The vulnerability also aligns with ATT&CK technique T1566, which covers social engineering tactics that leverage web-based attacks to compromise systems through user interaction.
Mitigation strategies for CVE-2024-11806 should prioritize immediate plugin updates to versions that address the input sanitization and output escaping deficiencies. WordPress administrators should implement comprehensive monitoring of their plugin installations to ensure all third-party components remain current with security patches. Additionally, implementing proper input validation and output escaping mechanisms, such as using WordPress's built-in sanitization functions like esc_attr() and esc_html(), can prevent similar vulnerabilities from occurring in the future. Network-level protections such as web application firewalls and content security policies can provide additional layers of defense, though these should not replace proper code-level remediation. Security teams should also conduct regular vulnerability assessments of their WordPress installations to identify and remediate similar issues before they can be exploited by threat actors.
