CVE-2022-24999
Description
A flaw was found in the express.js npm package of nodejs:14 module stream. Express.js Express is vulnerable to a denial of service caused by a prototype pollution flaw in qs. By adding or modifying properties of Object.prototype using a proto or constructor payload, a remote attacker can cause a denial of service.
Statement
- The qs and express Package is not used by the OpenShift Container Platform console directly and is only a third-party package dependency. Hence, it is marked as wontfix. As a result, any services that depend on Openshift for their use of qs and express are marked won't fix.
- In OpenShift Service Mesh, 'qs' is hoisted from storybook and node-sass, both are dev dependencies, and the vulnerability is not exposed to end users. Hence marked as wontfix.
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)
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.
