CVE-2024-39347
Incorrect default permissions vulnerability in firewall functionality in Synology Router Manager (SRM) before 1.2.5-8227-11 and 1.3.1-9346-8 allows man-in-the-middle attackers to access highly sensitive intranet resources via unspecified vectors.
Does this matter?
Lower severity and a low EPSS score (0.52%). Track it; it rarely justifies an emergency change on its own.
