Description

HtmlUtil.escapeRedirect in Liferay Portal 7.3.1 through 7.4.2, and Liferay DXP 7.0 fix pack 91 through 101, 7.1 fix pack 17 through 25, 7.2 fix pack 5 through 14, and 7.3 before service pack 3 can be circumvented by using multiple forward slashes, which allows remote attackers to redirect users to arbitrary external URLs via the (1) 'redirectparameter (2)FORWARD_URL` parameter, and (3) others parameters that rely on HtmlUtil.escapeRedirect.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.

Weaknesses

URL Redirection to Untrusted Site ('Open Redirect')

The web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect. Learn more on MITRE.
