Why this priority: Not scored yet, and no exploitation signal.

Published · Updated · NVD status: Received

What it is

Two operations race on shared state, and an attacker who wins the race bypasses a check or corrupts data.

How it is reached

The record does not say yet how the flaw is reached; the description below is the best guide until it is scored.

What an attacker gains

Its impact has not been scored yet. In practice, this kind of flaw lets an attacker win a timing window to bypass a check or corrupt shared state.

Is it being exploited?

There is no public report of exploitation yet.

What to do

  1. No fixed version is listed yet. Find every place Apache HTTP Server runs, watch the references for a fix, and plan a replacement if it is no longer supported.

Description from NVD

Concurrent Execution using Shared Resource with Improper Synchronization vulnerability in Apache HTTP Server's mod_http2 in assign_headers() can lead to RCE.

This issue affects Apache HTTP Server: from 2.4.55 through 2.4.70. Affected releases of mod_h2 from GitHub: from 2.0.8 through 2.0.42.

What this means for your architecture.

A CVE names a product. Whether it matters depends on where that product sits in your systems: what reaches it, which trust boundary it guards and what it can reach once compromised. Veriom maps your components, their relationships and your trust boundaries from your code, cloud and delivery evidence, so you can see where a component like this sits. The radar itself does not look at your systems.

Components it touches

  • Request handlers and jobs that share state. The flaw sits between concurrent requests or processes.

Trust boundaries in play

  • Between concurrent requests or processes. An attacker who crosses it can win a timing window to bypass a check or corrupt shared state.

Questions to answer about your own systems

  • Where does Apache HTTP Server run in your systems, and at which version?
  • Which of those instances are reachable by people you do not trust?
  • What can it reach once compromised: which data stores, secrets and services?
