Ensure 'ssoRequiresSSL' secure attribute is set to 'true' for the LTPA Cookies

AltaNivel 1Automatizadawebsphere

Descripción

Cookies with the secure flag will only be sent over encrypted HTTPS requests. 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. ssoRequiresSSL on <webAppSecurity> must be true. The attribute must be set explicitly because the Liberty default is not compliant.
