CVE-2020-24554
The redirect module in Liferay Portal before 7.3.3 does not limit the number of URLs resulting in a 404 error that is recorded, which allows remote attackers to perform a denial of service attack by making repeated requests for pages that do not exist.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.76%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
