CVE-2020-15842
Liferay Portal before 7.3.0, and Liferay DXP 7.0 before fix pack 90, 7.1 before fix pack 17, and 7.2 before fix pack 5, allows man-in-the-middle attackers to execute arbitrary code via crafted serialized payloads, because of insecure deserialization.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.78%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
