CVE-2022-4975
Description
A flaw was found in the Red Hat Advanced Cluster Security (RHACS) portal. When rendering a table view in the portal, for example, on any of the /main/configmanagement/* endpoints, the front-end generates a DOM table-element (id="pdf-table"). This information is then populated with unsanitized data using innerHTML. An attacker with some control over the data rendered can trigger a cross-site scripting (XSS) vulnerability.
Statement
To exploit this flaw, an attacker needs to be able to create a RHACS policy or an OpenShift cluster role with a specially crafted name. Additionally, the OpenShift cluster must be monitored by RHACS.
To perform these actions, an attacker needs to be authenticated, limiting the possibility of this issue to be exploited.
For this reason, this flaw has been rated with a Low severity.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
