Detection & IOCsextracted from sources · hover to see the quote

→Authentication bypass in Apache Shiro before 1.7.1 when used with Spring is triggered by a specially crafted HTTP request ↗

·Vulnerability only applies when Apache Shiro is used together with Spring; standalone Shiro deployments are not affected by this specific bypass vector ↗
·Red Hat OpenStack Platform's OpenDaylight includes the affected code but the vulnerable function is not used and therefore not exploitable; RHOSP impact is rated low and no update will be provided for OpenDaylight ↗
·The fix is present in Apache Shiro 1.7.1; any deployment running an earlier version with Spring integration should be considered vulnerable ↗
