Exploitation evidence

Disclosed: evidence found.
CVE published 20 Mar 2024
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-25.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

Upgrade SUSE to 21.6.2, 20.11.1, 18.19.1 or 16.20.2.

AI-suggested

Red Hat has released updated Node.js packages that fix this vulnerability. Users should apply the security updates provided in Red Hat Software Collections for RHEL 7 and Red Hat Enterprise Linux 9.0 Extended Update Support as detailed in advisories RHSA-2024:1354 and RHSA-2024:1424. Before applying these updates, ensure all previously released errata relevant to your system have been applied. Follow Red Hat's official guidance at https://access.redhat.com/articles/11258 for update procedures.

Description

A vulnerability in Node.js HTTP servers allows an attacker to send a specially crafted HTTP request with chunked encoding, leading to resource exhaustion and denial of service (DoS). The server reads an unbounded number of bytes from a single connection, exploiting the lack of limitations on chunk extension bytes. The issue can cause CPU and network bandwidth exhaustion, bypassing standard safeguards like timeouts and body size limits.

Impact

An attacker can exploit this vulnerability by sending HTTP requests with unbounded chunk extensions to cause denial of service, potentially exhausting server resources and disrupting service availability. There are no known exploits in the wild at this time. The impact is rated as high by Red Hat Product Security.

Summary

CVE-2024-22019 is a denial of service vulnerability in Node.js where reading unprocessed HTTP requests with unbounded chunk extensions can lead to resource exhaustion. This vulnerability is tracked by Red Hat and affects their Node.js packages distributed in Red Hat Software Collections for RHEL 7 and Red Hat Enterprise Linux 9.0 Extended Update Support. Red Hat has issued security advisories RHSA-2024:1354 and RHSA-2024:1424 providing updated packages that fix this issue. The vulnerability is classified under CWE-400 (Uncontrolled Resource Consumption).

CWE-400Uncontrolled Resource Consumption (opens in a new tab)
Class weaknessLikelihood of exploit: High
The product does not properly control the allocation and maintenance of a limited resource.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Architecture and Design
Design throttling mechanisms into the system architecture. The best protection is to limit the amount of resources that an unauthorized user can cause to be expended. A strong authentication and access control model will help prevent such attacks from occurring in the first place.
Architecture and Design
Mitigation of resource exhaustion attacks requires that the target system either: recognizes the attack and denies that user further access for a given amount of time, or; uniformly throttles all requests in order to make it more difficult to consume resources more quickly than they can again be freed.
Architecture and Design
Ensure that protocols have specific limits of scale placed on them.
