Question

During a web application assessment, your automated scanner flags two findings on the same target: (1) a reflected XSS in a search parameter rated Medium, and (1) 'Apache HTTP Server 2.4.29 - Multiple Vulnerabilities' rated Critical, based solely on the Server response header. The client's change records show the web tier was migrated to Nginx six months ago, sitting behind a reverse proxy. What is the most appropriate next step before including these in the report?

Accepted Answer

Manually confirm the reflected XSS by crafting a proof-of-concept payload, and investigate the Apache banner finding as a likely false positive caused by a misleading or spoofed header

Answer

Report both findings at their scanner-assigned severities, since the tool correlated them to known CVEs

Answer

Discard the XSS as a false positive because reflected XSS requires user interaction, and escalate the Apache Critical immediately

Answer

Rescan the target with a different tool and report only findings that appear in both scanners' output
