Exploitation evidence

Disclosed: evidence found.
CVE published 9 Oct 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

Official patches are available from Red Hat for .NET SDK 6.0.135 and .NET Runtime 6.0.35. Users should apply these updates promptly to remediate the denial of service vulnerabilities. Refer to Red Hat advisory RHSA-2024:7851 and the article https://access.redhat.com/articles/11258 for detailed update instructions. No additional mitigations are specified by the vendor.

Description

.NET, .NET Framework, and Visual Studio Denial of Service Vulnerability

Impact

Successful exploitation of these vulnerabilities can lead to denial of service conditions, causing affected applications or services to become unresponsive or crash. There is no impact on confidentiality or integrity reported. The CVSS 3.1 base score is 7.5 (high severity), indicating a significant availability impact with network attack vector and no privileges required.

Summary

This advisory covers three denial of service (DoS) vulnerabilities in .NET 6.0 components on Red Hat Enterprise Linux 8: CVE-2024-43483 (hash flooding in multiple .NET components), CVE-2024-43484 (multiple DoS vectors in System.IO.Packaging's use of SortedList), and CVE-2024-43485 (DoS in System.Text.Json). These vulnerabilities can cause application unavailability due to resource exhaustion. Red Hat has released official fixes in .NET SDK 6.0.135 and .NET Runtime 6.0.35 to address these issues.

CWE-407Inefficient Algorithmic Complexity (opens in a new tab)
Class weaknessLikelihood of exploit: Low
An algorithm in a product has an inefficient worst-case computational complexity that may be detrimental to system performance and can be triggered by an attacker, typically using crafted manipulations that ensure that the worst case is being reached.

CWE-770Allocation of Resources Without Limits or Throttling (opens in a new tab)
Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #25
The product allocates a reusable resource or group of resources on behalf of an actor without imposing any intended restrictions on the size or number of resources that can be allocated.
Requirements
Clearly specify the minimum and maximum expectations for capabilities, and dictate which behaviors are acceptable when resource allocation reaches limits.
Architecture and Design
Limit the amount of resources that are accessible to unprivileged users. Set per-user limits for resources. Allow the system administrator to define these limits. Be careful to avoid CWE-410.
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.
