CVE-2017-12161
An attacker could use this flaw to craft a malicious password reset request and gain a valid reset token, leading to information disclosure or further attacks.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.31%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
It was found that keycloak before 3.4.2 final would permit misuse of a client-side /etc/hosts entry to spoof a URL in a password reset request. An attacker could use this flaw to craft a malicious password reset request and gain a valid reset token, leading to information disclosure or further attacks.
