CVE-2019-17573Network attack vector

Script execution via unescaped service-list URLs

Published Jan 16, 2020 · Updated Aug 5, 2024

Reflected XSS in Apache CXF before 3.2.12 and 3.3.0 through 3.3.4 allows remote attackers to execute JavaScript. FormattedServiceListWriter and UnformattedServiceListWriter place request-derived endpoint URLs into service-list HTML without HTML escaping. Exploitation requires a victim client that preserves crafted dot segments; modern browsers remove them, while affected mobile clients execute script in the service origin.
