Reflected XSS vulnerability in keter
Keter is an app-server/reverse-proxy often used with webapps build on Yesod web-framework.
In the logic handling VHost dispatch, Keter was echoing back
Hostheader value, unescaped, as part of an HTML error page. This constitutes a reflected-XSS vulnerability. Although not readily exploitable directly from a browser (whereHostheader can't generally assume arbitrary values), it may become such in presence of further weaknesses in components upstream of Keter in the http proxying chain. Therefore, AC:High in CVSS evaluation. - Database specific
