HIGH 7.2

DescriptionCVE.org

The Quick Interest Slider plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'loan-amount' and 'loan-period' parameters in all versions up to, and including, 3.1.5 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

AnalysisAI

Stored Cross-Site Scripting in Quick Interest Slider plugin for WordPress (versions ≤3.1.5) allows unauthenticated remote attackers to inject malicious scripts via unsanitized 'loan-amount' and 'loan-period' parameters. Injected scripts execute in victim browsers when accessing compromised pages, enabling session hijacking, credential theft, or malicious redirects. CVSS 7.2 with network-accessible, low-complexity attack vector (AV:N/AC:L/PR:N) and scope change (S:C) indicates significant cross-tenant impact. No public exploit identified at time of analysis, though exploitation requires minimal technical sophistication due to unauthenticated attack surface.

Technical ContextAI

This vulnerability affects the Quick Interest Slider plugin (CPE: cpe:2.3:a:aerin:quick_interest_slider), a WordPress extension for displaying loan calculation interfaces. The flaw manifests as CWE-79 (Improper Neutralization of Input During Web Page Generation) in the plugin's parameter handling logic. Source code analysis references (lines 1335 and 1338 of quick-interest-slider.php in version 3.1.5) reveal insufficient input validation on user-supplied 'loan-amount' and 'loan-period' values before database storage and subsequent rendering. Unlike reflected XSS which requires immediate victim interaction, stored XSS persists the malicious payload in the WordPress database, causing automatic execution when any user-including administrators-views the affected page. The scope change (S:C) in the CVSS vector indicates the vulnerability can impact resources beyond the plugin's security boundary, potentially compromising the entire WordPress installation's integrity through admin session compromise.

RemediationAI

Immediately upgrade Quick Interest Slider plugin to version 3.1.6 or later if available through the WordPress plugin repository, as version 3.1.5 is confirmed vulnerable. Site administrators should access WordPress admin dashboard, navigate to Plugins section, and apply available updates. If a patched version is not yet released, implement temporary mitigation by deactivating and removing the Quick Interest Slider plugin until vendor releases a security update. As an alternative workaround, implement Web Application Firewall (WAF) rules to sanitize 'loan-amount' and 'loan-period' parameters, blocking requests containing HTML tags, JavaScript event handlers, or script tags-though this provides only partial protection. Conduct forensic review of existing database entries for these parameters to identify and remove any previously injected payloads, checking wp_postmeta and plugin-specific tables. Review WordPress access logs for suspicious POST requests to pages containing Quick Interest Slider shortcodes. Consult Wordfence advisory at https://www.wordfence.com/threat-intel/vulnerabilities/id/e3ce37e7-1dca-4f74-86ce-65bf29ef091e for updated remediation guidance and monitor the WordPress plugin repository for official security releases.
