CVE-2021-23358
Description
A flaw was found in nodejs-underscore. Arbitrary code execution via the template function is possible, particularly when a variable property is passed as an argument as it is not sanitized. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
Statement
Whilst the OpenShift Container Platform (OCP) openshift4/ose-grafana and openshift3/grafana as well as console, grc-ui and search-ui containers for Red Hat Advanced Management for Kubernetes (RHACM) include the vulnerable underscore library, the access to it is protected by OpenShift OAuth. Additionally this library is used in openshift4/ose-grafana container only in Grafana End-to-End Test package. Therefore the impact by this flaw is reduced to Low and the affected OCP components are marked as "will not fix" at this time and to Moderate for the affected RHACM components. This might be fixed in a future release.
Red Hat Enterprise Virtualization includes the vulnerable underscore library, however it is not parsing any untrusted data, therefore impact is reduced to Low.
Below Red Hat products include the underscore dependency, but it is not used by the product and hence this issue has been rated as having a security impact of Low.
- Red Hat Quay
- Red Hat Gluster Storage 3
- Red Hat OpenShift Container Storage 4
- Red Hat Ceph Storage 3 and 4
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).

Understanding the Weakness (CWE)
Access Control
Technical Impact: Bypass Protection Mechanism
In some cases, injectable code controls authentication; this may lead to a remote vulnerability.
Access Control
Technical Impact: Gain Privileges or Assume Identity
Injected code can access resources that the attacker is directly prevented from accessing.
Integrity,Confidentiality,Availability
Technical Impact: Execute Unauthorized Code or Commands
When a product allows a user's input to contain code syntax, it might be possible for an attacker to craft the code in such a way that it will alter the intended control flow of the product. As a result, code injection can often result in the execution of arbitrary code. Code injection attacks can also lead to loss of data integrity in nearly all cases, since the control-plane data injected is always incidental to data recall or writing.
Non-Repudiation
Technical Impact: Hide Activities
Often the actions performed by injected control code are unlogged.
