CVE-2020-25289
The VPN service in AVAST SecureLine before 5.6.4982.470 allows local users to write to arbitrary files via an Object Manager symbolic link from the log directory (which has weak permissions).
Does this matter?
Lower severity and a low EPSS score (0.45%). Track it; it rarely justifies an emergency change on its own.
