ID: CVE-2019-10092

Severity: medium

Author: pdteam

Tags: cve,cve2019,apache,htmli,injection

Description

Section titled “Description”

Apache HTTP Server versions 2.4.0 through 2.4.39 are vulnerable to a limited cross-site scripting issue affecting the mod_proxy error page. An attacker could cause the link on the error page to be malformed and instead point to a page of their choice. This would only be exploitable where a server was set up with proxying enabled but was misconfigured in such a way that the Proxy Error page was displayed.
