CVE-2020-28044
An attacker with physical access to a PAX Point Of Sale device with ProlinOS through 2.4.161.8859R can boot it in management mode, enable the XCB service, and then list, read, create, and overwrite files with MAINAPP permissions.
Does this matter?
Lower severity and a low EPSS score (0.34%). Track it; it rarely justifies an emergency change on its own.
