CVE-2022-1343

Description

A flaw was found in OpenSSL's Online Certificate Status Protocol (OCSP) response functionality in the signer certificate verification routines. This flaw could result in a linked application falsely believing that an x.509 Digital Certificate is either "good" or "unknown" when revoked and requires that the application use a non-default configuration. This vulnerability leads to an issue with data integrity and confidentiality.

Statement

This flaw impact has been rated Moderate because the configuration required for it to occur is non-default, not common, and there is still an indication of failure at the CLI for the OCSP application.

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)

Integrity,Authentication

Technical Impact: Bypass Protection Mechanism; Gain Privileges or Assume Identity

When a certificate is invalid or malicious, it might allow an attacker to spoof a trusted entity by interfering in the communication path between the host and client. The product might connect to a malicious host while believing it is a trusted host, or the product might be deceived into accepting spoofed data that appears to originate from a trusted host.
