CVE-2020-14301: An information disclosure vulnerability was found in libvirt in versions before 6.3.0.

An information disclosure vulnerability was found in libvirt in versions before 6.3.0. HTTP cookies used to access network-based disks were saved in the XML dump of the guest domain. This flaw allows an attacker to access potentially sensitive information in the domain configuration via the `dumpxml` command.

Security readout for executives and security teams

Plain-English summary

CVE-2020-14301 is an information disclosure issue in libvirt. In affected versions, HTTP cookies used to access network-based disks could be written into a virtual machine's XML configuration output. Anyone who can obtain that domain XML may see credentials that help access storage-backed virtual disks.

Executive priority

Treat this as a targeted credential exposure risk, not a broad remote compromise signal. Prioritize environments using libvirt with network-backed disks, especially where XML dumps are collected by automation, support workflows, or less-trusted operators.

Technical view

The flaw is tied to libvirt domain XML generation: cookies for network disk access were saved in dumpxml output. The weakness maps to CWE-212 and is described for libvirt versions before 6.3.0. The bundle does not provide CVSS metrics, exploit details, or a complete downstream product matrix.

Likely exposure

Exposure is most likely where libvirt manages guests using network-based disks that authenticate with HTTP cookies, and where users, tools, logs, or support bundles can access domain XML dumps.

Exploitation context

The provided sources do not show active exploitation, and the CVE is not marked KEV. Practical risk depends on whether an attacker already has access to domain configuration output or stored copies containing the leaked cookies.

Researcher notes

Key evidence is limited to the CVE description and references. No CVSS, proof of exploitation, or detailed affected downstream product list is provided in the bundle. The main validation focus is whether sensitive disk-access cookies appear in domain XML output.

Mitigation direction

  • Identify libvirt deployments managing network-based disks with HTTP cookie authentication.
  • Upgrade to a vendor-supported libvirt release containing the CVE-2020-14301 fix.
  • Review vendor advisories for platform-specific packages and backported fixes.
  • Restrict access to domain XML dumps, support bundles, logs, and automation outputs.
  • Rotate any exposed HTTP cookies or storage access credentials.

Validation and detection

  • Check installed libvirt versions against vendor advisories for CVE-2020-14301.
  • Review guest domain XML dumps for stored HTTP cookie values.
  • Search support bundles and logs for historical domain XML containing cookies.
  • Confirm only trusted administrators can run or retrieve domain XML dump output.
  • Verify credential rotation where leaked cookies were found.
