CVE-2020-14359 (GCVE-0-2020-14359)

Vulnerability from cvelistv5 – Published: 2021-02-23 12:42 – Updated: 2024-08-04 12:39

Summary

A vulnerability was found in all versions of Keycloak Gatekeeper, where on using lower case HTTP headers (via cURL) an attacker can bypass our Gatekeeper. Lower case headers are also accepted by some webservers (e.g. Jetty). This means there is no protection when we put a Gatekeeper in front of a Jetty server and use lowercase headers.

Severity ?

No CVSS data available.

Vulnerability from github – Published: 2022-02-09 00:56 – Updated: 2022-08-12 20:52

Summary

Keycloak Gatekeeper vulnerable to bypass on using lower case HTTP headers

Details

A vulnerability was found in all versions of the deprecated package Keycloak Gatekeeper, where on using lower case HTTP headers (via cURL) we can bypass our Gatekeeper. Lower case headers are also accepted by some webservers (e.g. Jetty). This means there is no protection when we put a Gatekeeper in front of a Jetty server and use lowercase headers.

Severity ?

7.3 (High)
