Comment 3 Ted Jongseok Won 2021-02-03 03:12:03 UTC

Marking Red Hat Fuse 7 as having a low impact, Fuse 7 distributes some shiro artifacts (shiro-core) as part of camel-shiro however these artifacts are not impacted by the vulnerability. 

Marking Red Hat JBoss Fuse 6 as having a moderate impact, Fuse 6 does distribute some shiro artifacts as part of camel-shiro, however these are not affected by the vulnerability, only components using shiro in the context of the spring web application portion of the shiro framework are affected and only the artifact org.apache.shiro:spring-boot-web-starter is altered in the fix version of shiro (1.7.1)


 This vulnerability is out of security support scope for the following products:
 * Red Hat JBoss Fuse 6
 * Red Hat JBoss A-MQ 6

Comment 5 RaTasha Tillery-Smith 2021-02-03 16:36:11 UTC

Statement:

Although Red Hat OpenStack Platform's OpenDaylight includes the affected code, the vulnerable function is not used and therefore not exploitable. For this reason, the RHOSP impact is low and no update will be provided at this time for OpenDaylight.
