Exploitation evidence

Disclosed: evidence found.
CVE published 18 Aug 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.

AI-suggested

Red Hat advises mitigating this vulnerability by using the SSH client only to connect to trusted servers. Users should monitor Red Hat advisories for future fixes and follow documented upgrade procedures for the Windows Machine Config Operator as referenced. No additional immediate actions are specified by the vendor.

Description

Red Hat OpenShift for Windows Containers allows you to deploy Windows container workloads running on Windows Server containers.

Impact

The vulnerability can cause denial of service through resource exhaustion (memory) on systems running affected versions of Red Hat OpenShift for Windows Containers. This may disrupt SSH connectivity and related container workloads. There is no impact on confidentiality or integrity reported. Exploitation likelihood is reduced due to the requirement for slow key exchange responses and large file transfers.

Summary

CVE-2025-22869 is a resource exhaustion vulnerability in the golang.org/x/crypto/ssh package used by Red Hat OpenShift for Windows Containers 10.19.0. The flaw occurs during SSH key exchange when the other party is slow to respond, leading to excessive memory consumption and a potential denial of service. Both SSH clients and servers using this package are affected, but practical exploitation is limited to scenarios involving large file transfers. The vulnerability is tracked under CWE-770 (Allocation of Resources Without Limits or Throttling). Red Hat's advisory notes the issue and provides mitigation guidance but does not confirm an available patch.

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-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.
