CVE-2022-48279

Description

A vulnerability was found in ModSecurity. This issue occurs when HTTP multipart requests are incorrectly parsed and could bypass the Web Application Firewall. NOTE: This is related to CVE-2022-39956, but can be considered independent changes to the ModSecurity (C language) codebase.

Statement

Red Hat rates this vulnerability as Moderate impact as a result of how mod_security is configured to be used in Red Hat products. When running with default configurations the affected program will have limited privileges and thus the impact of this flaw will be restricted beyond what the Web Application Firewall is also restricting.

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).
