Information disclosure vulnerability in the Control Panel in Liferay Portal 7.2.0 through 7.4.2, and older unsupported versions, and Liferay DXP 7.3 before update 4, 7.2 before fix pack 19, and older unsupported versions allows remote authenticated users to obtain a user's full name from the page's title by enumerating user screen names.
Liferay Portal 7.2.0 through 7.4.1, and older unsupported versions, and Liferay DXP 7.3 before service pack 3, 7.2 before fix pack 15, and older unsupported versions does not properly restrict membership of a child site when the "Limit membership to members of the parent site" option is enabled, which allows remote authenticated users to add users who are not a member of the parent site to a child site. The added user may obtain permission to perform unauthorized actions in the child site.
Liferay Portal before 7.4.3.16 and Liferay DXP before 7.2 fix pack 19, 7.3 before update 6, and 7.4 before update 16 allow remote authenticated users to become the owner of a wiki page by editing the wiki page.
Liferay Portal 7.2.0 through 7.4.1, and older unsupported versions, and Liferay DXP 7.3 before service pack 3, 7.2 before fix pack 18, and older unsupported versions returns with different responses depending on whether a site does not exist or if the user does not have permission to access the site, which allows remote attackers to discover the existence of sites by enumerating URLs. This vulnerability occurs if locale.prepend.friendly.url.style=2 and if a custom 404 page is used.
In Liferay Portal 7.2.0 through 7.4.1, and older unsupported versions, and Liferay DXP 7.3 before service pack 3, 7.2 before fix pack 15, and older unsupported versions the `doAsUserId` URL parameter may get leaked when creating linked content using the WYSIWYG editor and while impersonating a user. This may allow remote authenticated users to impersonate a user after accessing the linked content.
The IFrame widget in Liferay Portal 7.2.0 through 7.4.3.26, and older unsupported versions, and Liferay DXP 7.4 before update 27, 7.3 before update 6, 7.2 before fix pack 19, and older unsupported versions does not check the URL of the IFrame, which allows remote authenticated users to cause a denial-of-service (DoS) via a self referencing IFrame.
Account lockout in Liferay Portal 7.2.0 through 7.3.0, and older unsupported versions, and Liferay DXP 7.2 before fix pack 5, and older unsupported versions does not invalidate existing user sessions, which allows remote authenticated users to remain authenticated after an account has been locked.
Stored cross-site scripting (XSS) vulnerability in the Wiki widget in Liferay Portal 7.1.0 through 7.4.3.87, and Liferay DXP 7.0 fix pack 83 through 102, 7.1 fix pack 28 and earlier, 7.2 fix pack 20 and earlier, 7.3 update 33 and earlier, and 7.4 before update 88 allows remote attackers to inject arbitrary web script or HTML into a parent wiki page via a crafted payload injected into a wiki page's ‘Content’ text field.
In Liferay Portal 7.3.0 and earlier, and Liferay DXP 7.2 and earlier the default configuration does not require users to verify their email address, which allows remote attackers to create accounts using fake email addresses or email addresses which they don't control. The portal property `company.security.strangers.verify` should be set to true.
Cross-site scripting (XSS) vulnerability in the Modified Facet widget in Liferay Portal 7.1.0 through 7.4.3.12, and Liferay DXP 7.1 before fix pack 27, 7.2 before fix pack 18, 7.3 before update 4, and 7.4 before update 9 allows remote attackers to inject arbitrary web script or HTML via a crafted payload injected into a facet label.
