Last modified
CVE-2017-2582 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. 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.. EPSS estimates a 2.46% chance of exploitation in the next 30 days.
