Summary
by MITRE • 06/07/2024
The Logo Slider WordPress plugin before 4.0.0 does not validate and escape some of its Slider Settings before outputting them back in attributes, which could allow users with the contributor role and above to perform Stored Cross-Site Scripting attacks

The vulnerability identified as CVE-2024-3288 affects the Logo Slider WordPress plugin version 4.0.0 and earlier, presenting a critical security risk through stored cross-site scripting attacks. This issue stems from inadequate input validation and output escaping mechanisms within the plugin's Slider Settings functionality, creating an attack vector that can be exploited by users holding the contributor role or higher privileges. The vulnerability specifically targets the plugin's handling of user-provided data in slider configuration parameters, where malicious scripts can be injected and subsequently executed when the slider settings are rendered on web pages.
The technical flaw manifests in the plugin's failure to properly sanitize and escape slider settings before these values are written back into HTML attributes during page rendering. This represents a classic stored XSS vulnerability pattern where malicious input is first stored in the database and then executed in subsequent page requests. The vulnerability falls under CWE-79 - Improper Neutralization of Input During Web Page Generation, which is a fundamental weakness in web application security that allows attackers to inject malicious scripts into web pages viewed by other users. The attacker with contributor privileges can leverage this weakness to inject malicious JavaScript code into slider configuration fields, which then gets executed in the browsers of other users who view pages containing the vulnerable slider.
The operational impact of this vulnerability is significant as it allows attackers to escalate their privileges and potentially compromise entire WordPress installations. A contributor-level attacker can inject persistent malicious scripts that can perform various malicious activities including session hijacking, data theft, defacement of website content, or redirection to malicious sites. The stored nature of the XSS means that the malicious code remains active even after the initial injection, continuously affecting all users who access pages containing the vulnerable slider. This vulnerability can be particularly dangerous in multi-user environments where contributors may have access to sensitive configuration data or where the slider is used in public-facing sections of websites.
Mitigation strategies for CVE-2024-3288 should prioritize immediate plugin updates to version 4.0.0 or later, which contain the necessary security patches to address the input validation and output escaping issues. System administrators should also implement additional security measures including role-based access controls to limit contributor privileges where possible, regular security audits of installed plugins, and monitoring for suspicious activities in slider configuration settings. The vulnerability demonstrates the importance of proper input validation and output escaping as outlined in the OWASP Top Ten and aligns with ATT&CK technique T1566.001 - Phishing: Spearphishing Attachment, as attackers may use the XSS to deliver malicious payloads through compromised slider configurations. Organizations should also consider implementing Content Security Policy headers to add an additional layer of protection against XSS attacks, though this should not be considered a substitute for proper input validation and sanitization within the application code itself.
