Description
CubeCart is an ecommerce software solution. Prior to 6.7.0, an unauthenticated Reflected XSS vulnerability exists in the CubeCart v6.x search feature. Due to a logic flaw in classes/catalogue.class.php, user input is reflected without sanitization only when a search returns exactly one product. This flaw bypasses current filters, allowing an attacker to execute malicious JavaScript in the victim's browser, leading to session hijacking, site defacement, or phishing. This vulnerability is fixed in 6.7.0.

AI Analysis

Impact

The vulnerability is a reflected cross-site scripting flaw in the CubeCart v6 search feature that occurs only when a single product is returned. An unauthenticated attacker can craft a search query containing malicious JavaScript that is reflected back to the browser without sanitization, enabling session hijacking, site defacement, or phishing. This weakness is classified as CWE-79.

Affected Systems

CubeCart v6.x versions earlier than 6.7.0 are vulnerable. The flaw exists in the classes/catalogue.class.php file and affects the default search bar of the CubeCart e-commerce platform.

Risk and Exploitability

The CVSS score of 6.1 indicates moderate severity. EPSS is not available, but the attack requires only a simple crafted URL that can be distributed over email or social media. The vulnerability has not been listed in the CISA KEV catalog, and no public exploits are reported, yet its potential for cross-site scripting makes it a plausible threat to any site exposing the search endpoint to unauthenticated users.

OpenCVE Recommended Actions

  • Upgrade CubeCart to version 6.7.0 or later.
