CVSS v3.1

Official Description

An issue was discovered in Cloudera Manager 5.x through 5.15.0. One type of page in Cloudera Manager uses a 'returnUrl' parameter to redirect the user to another page in Cloudera Manager once a wizard is completed. The validity of this parameter was not checked. As a result, the user could be automatically redirected to an attacker's external site or perform a malicious JavaScript function that results in cross-site scripting (XSS). This was fixed by not allowing any value in the returnUrl parameter with patterns such as http://, https://, //, or javascript. The only exceptions to this rule are the SAML Login/Logout URLs, which remain supported since they are explicitly configured and they are not passed via the returnUrl parameter.

Technical Analysis

CVE-2018-15913 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation does not require any privileges, though user interaction (Required) is needed, which slightly reduces the risk of mass automated attacks.

The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.

From a weakness classification perspective (CWE-79): Cross-site scripting (XSS) vulnerabilities allow attackers to inject malicious scripts into web pages viewed by other users.
