CVE-2019-19002Network attack vector

Weakened browser XSS defenses via missing header

Published Apr 2, 2020 · Updated Aug 5, 2024

Security misconfiguration in Hitachi Energy eSOMS 4.0 through 6.0.2 leaves older browsers without an XSS response filter. The eSOMS web server omits the X-XSS-Protection header, so browsers without Content Security Policy receive no request to enable their legacy reflective-XSS filter. Exploitation requires an otherwise reachable script-injection path and user interaction; the published record does not identify that injection locus.
