Ensure 'displayAuthenticationRealm' is set to 'false'

ВысокийУровень 1Автоматическаяwebsphere

Описание

Configuring displayAuthenticationRealm will ensure that the registry information is not displayed in the login prompt. This will restrict the potential leak of security realm information. Audit: reads server.xml, configDropins/defaults/*.xml, configDropins/overrides/*.xml and files pulled in with <include> for every Liberty server found under WLP_USER_DIR, /opt/ibm/wlp/usr, /opt/IBM/WebSphere/Liberty/usr, /opt/ol/wlp/usr, /usr/local/wlp/usr or /config; it ignores XML comments and fails if no server.xml is readable. displayAuthenticationRealm must not be true. An unset attribute is accepted because the Liberty default is compliant.

Как исправляется

Set the displayAuthenticationRealm attribute in the webAppSecurity element to false in ${server.config.dir}/configDropins/overrides/<any file name>.xml. <webAppSecurity ... displayAuthenticationRealm="false" />
