Apache HTTP Server Patches Critical HTTP/2 RCE Flaw
What Happened
Apache HTTP Server has patched a critical vulnerability in its HTTP/2 module that, according to BleepingComputer, could allow an unauthenticated attacker to achieve remote code execution (RCE). Specific technical details of the flaw, the affected version range, and a CVE identifier were not included in the available reporting at this time.
Why It Matters
Apache HTTP Server is one of the most widely deployed web servers on the internet, and HTTP/2 is used in many production environments. A critical, unauthenticated RCE in this component would be a severe risk. Successful exploitation could grant an attacker code execution on internet-facing web servers without requiring credentials. This could affect any organization running an unpatched, HTTP/2-enabled Apache instance.
What Defenders Should Do Now
- Identify all internet-facing and internal systems running Apache HTTP Server with the HTTP/2 module (
mod_http2) enabled. - Prioritize patching to the latest Apache HTTP Server release once the specific fixed version is confirmed via the official Apache advisory.
- Where immediate patching is not possible, consider temporarily disabling HTTP/2 or restricting exposure via WAF or reverse proxy rules as a stopgap.
- Monitor web server logs and crash or error logs for anomalous HTTP/2 frame patterns, unexpected worker process crashes, or restarts that could indicate exploitation attempts.
- Review network and EDR telemetry on web server hosts for unexpected outbound connections or process spawning from the Apache worker processes following web requests.
Developing Story
This is a new advisory and details are still emerging, including the precise CVE identifier, affected version range, and technical root cause. Defenders should monitor the official Apache HTTP Server security advisories for authoritative patching guidance and track further reporting. Source: BleepingComputer.
