Exploitation evidence

Disclosed: evidence found.
CVE published 11 Sep 2025
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 Red Hat to 4.12.80.

AI-suggested

A fix is available in Red Hat OpenShift Container Platform version 4.12.80. Users should upgrade to this version using the OpenShift CLI or web console as per Red Hat's documented upgrade instructions. The vendor manages remediation for this on-premise/private cloud platform via updated container images and RPM packages. No additional mitigations are specified beyond applying the official update.

Description

Red Hat OpenShift Container Platform is Red Hat's cloud computing Kubernetes application platform solution designed for on-premise or private cloud deployments. This advisory contains the container images for Red Hat OpenShift Container Platform 4.12.80. See the following advisory for the RPM packages for this release: https://access.redhat.com/errata/RHBA-2025:15307 Space precludes documenting all of the container images in this advisory. See the following Release Notes documentation, which will be updated shortly for this release, for details about these changes: https://docs.redhat.com/en/documentation/openshift_container_platform/4.12/html/release_notes Security Fix(es): * golang.org/x/net/html: Non-linear parsing of case-insensitive content in golang.org/x/net/html (CVE-2024-45338) * golang-jwt/jwt: jwt-go allows excessive memory allocation during header parsing (CVE-2025-30204) * github.com/golang/glog: Vulnerability when creating log files in github.com/golang/glog (CVE-2024-45339) 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. To check for available updates, use the OpenShift CLI (oc) or web console. Instructions for upgrading a cluster are available at https://docs.redhat.com/en/documentation/openshift_container_platform/4.12/html-single/updating_clusters/index#updating-cluster-within-minor.

Impact

An attacker can cause denial of service by sending specially crafted input that triggers non-linear parsing in the vulnerable HTML parsing library, leading to resource exhaustion (CPU and memory). This affects availability of the affected OpenShift Container Platform deployments. There is no impact on confidentiality or integrity. No known exploits in the wild have been reported.

Summary

CVE-2024-45338 is a vulnerability in the golang.org/x/net/html package used by Red Hat OpenShift Container Platform. The flaw allows an attacker to craft input that causes the HTML parsing functions to process data non-linearly relative to input length, resulting in significant delays and excessive resource consumption (CPU and memory). This can lead to denial of service by exhausting system resources. Red Hat has released OpenShift Container Platform 4.12.80 containing updated container images and packages that fix this vulnerability. The advisory also addresses other vulnerabilities in golang-jwt/jwt and github.com/golang/glog. The vulnerability is rated as Important by Red Hat with a CVSS v3 base score of 7.5 (availability impact high, no confidentiality or integrity impact).

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.

Base weaknessLikelihood of exploit: MediumOWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.

Follow the principle of least privilege when assigning access rights to entities in a software system.

CWE-405Asymmetric Resource Consumption (Amplification) (opens in a new tab)
Class weakness
The product does not properly control situations in which an adversary can cause the product to consume or produce excessive resources without requiring the adversary to invest equivalent work or otherwise prove authorization, i.e., the adversary's influence is "asymmetric."
Architecture and Design
An application must make resources available to a client commensurate with the client's access level.
Architecture and Design
An application must, at all times, keep track of allocated resources and meter their usage appropriately.
System Configuration
Consider disabling resource-intensive algorithms on the server side, such as Diffie-Hellman key exchange.
