CVE-2021-47703
OpenBMCS 2.4 contains an unauthenticated SSRF vulnerability that allows attackers to bypass firewalls and initiate service and network enumeration on the internal network through the affected application, allowing hijacking of current sessions.
Does this matter?
Lower severity and a low EPSS score (0.32%). Track it; it rarely justifies an emergency change on its own.
