Stored cross-site scripting (XSS) vulnerability in the Portal Search module's Search Result app in Liferay Portal 7.2.0 through 7.4.3.11, and older unsupported versions, and Liferay DXP 7.4 before update 8, 7.3 before update 4, 7.2 before fix pack 17, and older unsupported versions allows remote authenticated users to inject arbitrary web script or HTML into the Search Result app's search result if highlighting is disabled by adding any searchable content (e.g., blog, message board message, web content article) to the application.

Multiple cross-site scripting (XSS) vulnerabilities in Liferay Portal v7.4.3.4 and Liferay DXP v7.4 GA allows attackers to execute arbitrary web scripts or HTML via parameters with the filter_ prefix.

Cross-site scripting (XSS) vulnerability in the Server module's script console in Liferay Portal 7.3.2 and earlier, and Liferay DXP 7.0 before fix pack 101, 7.1 before fix pack 20 and 7.2 before fix pack 10 allows remote attackers to inject arbitrary web script or HTML via the output of a script.

The Portal Workflow module in Liferay Portal 7.3.2 and earlier, and Liferay DXP 7.0 before fix pack 93, 7.1 before fix pack 19 and 7.2 before fix pack 6, does not properly check user permission, which allows remote authenticated users to view and delete workflow submissions via crafted URLs.

Cross-site scripting (XSS) vulnerability in the Frontend JS module in Liferay Portal 7.3.4 and earlier, and Liferay DXP 7.0 before fix pack 96, 7.1 before fix pack 20 and 7.2 before fix pack 9, allows remote attackers to inject arbitrary web script or HTML via the title of a modal window.

The Portal Workflow module in Liferay Portal 7.3.2 and earlier, and Liferay DXP 7.0 before fix pack 93, 7.1 before fix pack 19, and 7.2 before fix pack 7, user's clear text passwords are stored in the database if workflow is enabled for user creation, which allows attackers with access to the database to obtain a user's password.

In Liferay Portal 7.3.0 and earlier, and Liferay DXP 7.0 before fix pack 96, 7.1 before fix pack 18, and 7.2 before fix pack 5, password reset tokens are not invalidated after a user changes their password, which allows remote attackers to change the user’s password via the old password reset token.

The Flags module in Liferay Portal 7.3.1 and earlier, and Liferay DXP 7.0 before fix pack 96, 7.1 before fix pack 20, and 7.2 before fix pack 5, does not limit the rate at which content can be flagged as inappropriate, which allows remote authenticated users to spam the site administrator with emails

The JSON web services in Liferay Portal 7.3.4 and earlier, and Liferay DXP 7.0 before fix pack 97, 7.1 before fix pack 20 and 7.2 before fix pack 10 may provide overly verbose error messages, which allows remote attackers to use the contents of error messages to help launch another, more focused attacks via crafted inputs.

In Liferay Portal before 7.3.1, Liferay Portal 6.2 EE, and Liferay DXP 7.2, DXP 7.1 and DXP 7.0, the property 'portlet.resource.id.banned.paths.regexp' can be bypassed with doubled encoded URLs.

Liferay Portal before 7.3.3, and Liferay DXP 7.1 before fix pack 18 and 7.2 before fix pack 6, does not restrict the size of a multipart/form-data POST action, which allows remote authenticated users to conduct denial-of-service attacks by uploading large files.

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.

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.

Liferay Portal before 7.3.0, and Liferay DXP 7.0 before fix pack 89, 7.1 before fix pack 17, and 7.2 before fix pack 4, does not safely test a connection to a LDAP server, which allows remote attackers to obtain the LDAP server's password via the Test LDAP Connection feature.

Liferay Portal through 7.2.0 GA1 allows XSS via a journal article title to journal_article/page.jsp in journal/journal-taglib.

Liferay 6.2.x and before has an FCKeditor configuration that allows an attacker to upload or transfer files of dangerous types that can be automatically processed within the product's environment via a browser/liferay/browser.html?Type= or html/js/editor/fckeditor/editor/filemanager/browser/liferay/browser.html URI. NOTE: the vendor disputes this issue because file upload is an expected feature, subject to Role Based Access Control checks where only authenticated users with proper permissions can upload files

Liferay Portal through 6.2.10 allows remote authenticated users to execute arbitrary shell commands via a crafted Velocity template.

Cross-site scripting (XSS) vulnerability in Liferay Portal before 5.3.0 allows remote attackers to inject arbitrary web script or HTML via the p_p_id parameter.
