The advisory explicitly lists specific files and parameters vulnerable to reflected/stored XSS due to insufficient input sanitization and output encoding. Each entry corresponds to a script that processes user-supplied parameters (e.g., via $_GET, $_POST, or PATH_INFO) and injects them into the HTML response without proper escaping. High confidence stems from the detailed parameter/file mappings in the CVE description and Wizlynx report, including proof-of-concept payloads demonstrating exploitation.
