What is CVE-2020-15839?

Liferay Portal versions prior to 7.3.3, along with Liferay DXP 7.1 earlier than fix pack 18 and 7.2 prior to fix pack 6, are susceptible to a denial-of-service vulnerability. This occurs due to inadequate restrictions on the size of multipart/form-data POST requests, allowing remote authenticated users to perform malicious uploads of large files. Such actions can lead to service disruption, making it essential for users of the affected products to apply the recommended patches and mitigate potential risks.
