Security readout for executives and security teams

Plain-English summary

CVE-2015-5305 is a directory traversal flaw in Kubernetes as used by Red Hat OpenShift Enterprise 3.0. The reported impact is that an attacker could cause writes to arbitrary files using a crafted object type name before data is passed to etcd. The supplied sources do not provide CVSS, affected version range, or exploitation evidence.

Executive priority

Treat this as a legacy-platform risk item. If OpenShift Enterprise 3.0 or matching 2015 Kubernetes components remain in service, prioritize remediation or retirement. If those systems are absent, urgency is low but should be documented.

Technical view

The vulnerability concerns improper handling of an object type name before Kubernetes passes it to etcd. The CVE description characterizes this as directory traversal enabling arbitrary file writes. Public source details are limited to the CVE record, a Red Hat Bugzilla entry, and Red Hat advisory RHSA-2015:1945.

Likely exposure

Most likely exposure is legacy Red Hat OpenShift Enterprise 3.0 deployments or Kubernetes components matching that product’s 2015 affected build. The source bundle does not identify other affected Kubernetes versions, authentication requirements, or CPEs.

Exploitation context

The supplied data does not show active exploitation. The CVE is not listed as KEV in the bundle, and no cited source in the bundle states known exploitation or public weaponization.

Researcher notes

Evidence is sparse: no CVSS, CWE, affected CPEs, exploit status, or detailed patch notes are included in the source bundle. Analysis should stay bounded to Kubernetes as used in Red Hat OpenShift Enterprise 3.0 and RHSA-2015:1945.

Mitigation direction

  • Review RHSA-2015:1945 and apply the relevant Red Hat vendor updates.
  • Confirm OpenShift Enterprise 3.0 systems are upgraded or retired.
  • Restrict cluster administration and object creation privileges to trusted users.
  • Check Red Hat guidance for any product-specific remediation details.
  • Prioritize replacement of unsupported OpenShift or Kubernetes versions.

Validation and detection

  • Inventory OpenShift Enterprise and Kubernetes versions across clusters.
  • Compare installed Red Hat packages against RHSA-2015:1945 applicability.
  • Review etcd and API audit logs for unusual object type names.
  • Check hosts for unexpected file changes around cluster control-plane components.
  • Document any unsupported legacy clusters for remediation tracking.
