DescriptionCVE.org

Reflected Cross-Site Scripting (XSS) in the latest demo version of the Cradle eCommerce platform. User-controlled input is insecurely reflected in the HTML output in the endpoint /product/. Exploitation of this vulnerability would allow an attacker to execute arbitrary JavaScript code.

AnalysisAI

Reflected cross-site scripting (XSS) in Cradle eCommerce platform allows unauthenticated remote attackers to execute arbitrary JavaScript in users' browsers via crafted input to the /product/ endpoint. The vulnerability requires user interaction (clicking a malicious link) and affects the latest demo version. A vendor patch is available.

Technical ContextAI

The vulnerability stems from CWE-79 (Improper Neutralization of Input During Web Page Generation), a classic reflected XSS flaw where user-controlled input is echoed directly into HTML output without sanitization or encoding. The /product/ endpoint accepts attacker-supplied parameters and reflects them in the response, allowing script injection. Affected product identified via CPE as cpe:2.3:a:e-commerce:cradle:*:*:*:*:*:*:*:* (all versions of Cradle by e-commerce vendor). The CVSS 4.0 vector confirms network-accessible endpoint with no authentication required, though user interaction is necessary for successful exploitation.

RemediationAI

Apply the vendor-released patch immediately, available from INCIBE advisory at https://www.incibe.es/en/incibe-cert/notices/aviso/multiple-vulnerabilities-cradle-e-commerce. Exact patched version number not specified in provided data; confirm version compatibility through vendor documentation. As compensating controls pending patch deployment: implement input validation and output encoding on the /product/ endpoint to neutralize user-supplied data (sanitize input against XSS patterns, HTML-encode all reflected output); deploy Web Application Firewall (WAF) rules blocking script payloads in /product/ parameters; consider Content Security Policy (CSP) headers to prevent inline script execution (trade-off: may affect legitimate functionality); restrict access to /product/ endpoint to trusted IP ranges if business logic permits. These controls reduce but do not eliminate risk of sophisticated bypasses; patching remains the definitive remediation.
