Exploitation evidence

Disclosed: evidence found.
CVE published 29 May 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.

AI-suggested

Red Hat has released an official security update fixing this vulnerability in the rh-nodejs14-nodejs package for Red Hat Software Collections on RHEL 7. Users should apply the update as described in the Red Hat advisory (RHSA-2024:3472) and the referenced article https://access.redhat.com/articles/11258. No additional mitigation steps are indicated beyond applying the official patch.

Description

Node.js is a software development platform for building fast and scalable network applications in the JavaScript programming language. Security Fix(es): * rh-nodejs14-nodejs: CONTINUATION frames DoS (CVE-2024-27983) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Impact

Successful exploitation of this vulnerability could allow an attacker to cause a denial of service condition by exhausting resources via specially crafted CONTINUATION frames. This would disrupt the availability of Node.js applications running on affected Red Hat Software Collections environments.

Summary

CVE-2024-27983 is a denial of service vulnerability in the rh-nodejs14-nodejs package caused by improper handling of CONTINUATION frames. This can lead to resource exhaustion and service disruption. Red Hat has released a security update (RHSA-2024:3472) for Red Hat Software Collections on RHEL 7 across x86_64, s390x, and ppc64le architectures to fix this issue. The advisory rates the impact as Important (high severity). No CVSS score is provided in the advisory. The vulnerability is tracked under CWE-400, indicating a resource exhaustion type flaw.

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.
