Exploitation evidence

Disclosed: evidence found.
CVE published 3 Jun 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 updated Node.js packages for Red Hat Enterprise Linux 9.0 that fix these vulnerabilities. Users should apply these updates promptly. Before applying this update, ensure all previously released errata relevant to the system have been applied. Detailed update instructions are available from Red Hat's documentation. No additional mitigation steps are indicated beyond applying the official update.

Description

Node.js is a software development platform for building fast and scalable network applications in the JavaScript programming language. Security Fix(es): * nodejs: HTTP Request Smuggling via Content Length Obfuscation (CVE-2024-27982) * 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

The vulnerabilities could allow an attacker to perform HTTP request smuggling attacks, potentially leading to unexpected request handling behavior, and cause denial of service conditions via malformed CONTINUATION frames. The advisory rates the overall security impact as Important (high severity). No known exploits in the wild have been reported at this time.

Summary

This advisory covers two security vulnerabilities in Node.js as packaged by Red Hat for Red Hat Enterprise Linux 9.0. CVE-2024-27982 involves HTTP Request Smuggling through Content Length obfuscation, which can lead to request handling anomalies. CVE-2024-27983 is a Denial of Service vulnerability triggered by CONTINUATION frames. Red Hat has released updated Node.js packages (version 16.20.2-6.el9_0) to address these issues. The advisory references bug fixes BZ-2275392 and BZ-2272764 for these CVEs respectively. No CVSS scores are provided in the advisory.

CWE-444Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') (opens in a new tab)
Base weaknessOWASP Top 10 A06:2025: Insecure Design (opens in a new tab)
The product acts as an intermediary HTTP agent (such as a proxy or firewall) in the data flow between two entities such as a client and server, but it does not interpret malformed HTTP requests or responses in ways that are consistent with how the messages will be processed by those entities that are at the ultimate destination.
Implementation
Use a web server that employs a strict HTTP parsing procedure, such as Apache.
Implementation
Use only SSL communication.
Implementation
Terminate the client session after each request.

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.
