CVE-2017-2582

Severity CVSS v4.0:

Pending analysis

Type:

CWE-200 Information Leak / Disclosure

Publication date:

26/07/2018

Last modified:

Description

It was found that while parsing the SAML messages the StaxParserUtil class of keycloak before 2.5.1 replaces special strings for obtaining attribute values with system property. This could allow an attacker to determine values of system properties at the attacked system by formatting the SAML request ID field to be the chosen system property which could be obtained in the "InResponseTo" field in the response.
