CVE-2022-37601
Description
A prototype pollution vulnerability was found in the parseQuery function in parseQuery.js in the webpack loader-utils via the name variable in parseQuery.js. This flaw can lead to a denial of service or remote code execution.
Statement
Packages shipped in Red Hat Enterprise Linux use 'loader-utils' as a transitive dependency. Thus, reducing the impact to Moderate.
In Red Hat containerized products like OCP and ODF, the vulnerable loader-utils NodeJS module is bundled as a transitive dependency, hence the direct impact is reduced to Moderate.
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).

Red Hat CVSS v3 Score Explanation
A successful attack for this flaw would necessitate lack of input sanitization and restrictions in an implementing software or component. This is best reflected by a scoring metric of Access Complexity: High rather than Low.
Understanding the Weakness (CWE)
Confidentiality,Integrity,Availability
Technical Impact: Read Application Data; Modify Application Data
This weakness is usually exploited by using a special attribute of objects called proto, constructor, or prototype. Such attributes give access to the object prototype. An attacker can inject attributes that are used in other components by adding or modifying attributes of an object prototype. This creates attributes that exist on every object, or replace critical attributes with malicious ones. This can be problematic if the product depends on existence or non-existence of certain attributes, or uses pre-defined attributes of the object prototype (such as hasOwnProperty, toString, or valueOf).
Availability
Technical Impact: DoS: Crash, Exit, or Restart
An attacker can override existing attributes with ones that have incompatible type, which may lead to a crash.
