Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Liferay Portal 7.2.0 through 7.4.3.15 and Liferay DXP 7.4 before update 16, 7.3 before update 4, and 7.2 before fix pack 17 use a low work factor for the default PBKDF2-HMAC-SHA1 password hashing. An attacker who obtains stored password hashes can crack them quickly. Upgrade to Liferay DXP 7.4 update 16, 7.3 update 4, or 7.2 fix pack 17 (or later), or to Liferay Portal 7.4.3.14 (or later).
