Exploitation evidence

Disclosed: evidence found.
CVE published 17 Jun 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 2026-10-26.

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 4.20.0.

AI-suggested

Red Hat has released updated RPM packages and container images for OpenShift Container Platform 4.19.0 that address these vulnerabilities. Users are advised to upgrade to these updated packages and images through the appropriate release channels using the OpenShift CLI or web console. Detailed upgrade instructions are available in Red Hat's official documentation. Since this is an official security advisory with fixes available, applying these updates is the recommended mitigation.

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 RPM packages for Red Hat OpenShift Container Platform 4.19.0. See the following advisory for the container images for this release: https://access.redhat.com/errata/RHSA-2024:11038 Security Fix(es): * golang.org/x/crypto/ssh: Misuse of ServerConfig.PublicKeyCallback may cause authorization bypass in golang.org/x/crypto (CVE-2024-45337) * golang.org/x/net/html: Non-linear parsing of case-insensitive content in golang.org/x/net/html (CVE-2024-45338) * golang.org/x/oauth2/jws: Unexpected memory consumption during token parsing in golang.org/x/oauth2/jws (CVE-2025-22868) * golang.org/x/crypto/ssh: Denial of Service in the Key Exchange of golang.org/x/crypto/ssh (CVE-2025-22869) 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/4.19/html-single/updating_clusters/index#updating-cluster-cli.

Impact

The vulnerabilities may allow an attacker to bypass authorization checks, cause denial of service, or trigger unexpected memory consumption, potentially impacting the availability and security of the OpenShift Container Platform 4.19 deployments. The issues affect critical components related to SSH, HTML parsing, and OAuth2 token handling within the platform's dependencies. Red Hat rates the security impact as Important (high severity). There are no known exploits in the wild at the time of this advisory.

Summary

This advisory covers security fixes in Red Hat OpenShift Container Platform 4.19.0 for four vulnerabilities: CVE-2024-45337 (authorization bypass due to misuse of ServerConfig.PublicKeyCallback in golang.org/x/crypto/ssh), CVE-2024-45338 (non-linear parsing of case-insensitive content in golang.org/x/net/html), CVE-2025-22868 (unexpected memory consumption during token parsing in golang.org/x/oauth2/jws), and CVE-2025-22869 (denial of service in the key exchange of golang.org/x/crypto/ssh). These vulnerabilities affect the underlying Go libraries used by OpenShift and could impact the security and stability of the platform. The advisory includes RPM package updates and container image updates to address these issues.

CWE-285Improper Authorization (opens in a new tab)
Class weaknessLikelihood of exploit: HighOWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Architecture and Design
Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries.
Architecture and Design
Ensure that you perform access control checks related to your business logic. These checks may be different than the access control checks that you apply to more generic resources such as files, connections, processes, memory, and database records.
Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.

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.

CWE-1286Improper Validation of Syntactic Correctness of Input (opens in a new tab)
Base weakness
The product receives input that is expected to be well-formed - i.e., to comply with a certain syntax - but it does not validate or incorrectly validates that the input complies with the syntax.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
