CVE-2025-22871

Description

A flaw was found in the net/http golang package. The net/http package incorrectly accepts messages that end with a line feed (LF) instead of the proper line ending. When used with another server that also misinterprets this, it can lead to request smuggling—where an attacker tricks the system to send hidden or unauthorized requests.

Statement

Red Hat Satellite is rated as Low severity for this vulnerability. However, other affected components remain Moderate. Satellite uses the affected Go net/http component solely as a client to make requests, not as a server. Since this vulnerability only affects server-side usage, Satellite is not directly exposed to the flaw, justifying the lower severity rating.

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).

Understanding the Weakness (CWE)

Integrity,Non-Repudiation,Access Control

Technical Impact: Unexpected State; Hide Activities; Bypass Protection Mechanism

An attacker could create HTTP messages to exploit a number of weaknesses including 1) the message can trick the web server to associate a URL with another URL's webpage and caching the contents of the webpage (web cache poisoning attack), 2) the message can be structured to bypass the firewall protection mechanisms and gain unauthorized access to a web application, and 3) the message can invoke a script or a page that returns client credentials (similar to a Cross Site Scripting attack).
