CVE-2014-1428: uuid.uuid1() is not suitable as an unguessable identifier/token

A vulnerability in generate_filestorage_key of Ubuntu MAAS allows an attacker to brute-force filenames. This issue affects Ubuntu MAAS versions prior to 1.9.2.

Security readout for executives and security teams

Plain-English summary

Ubuntu MAAS used a UUID generation method that was not appropriate for secret file-storage identifiers. In affected versions before 1.9.2, a highly privileged attacker with adjacent access could potentially guess filenames and read limited information. The reported severity is low, with no cited evidence of active exploitation.

Executive priority

Treat this as low-priority technical debt unless legacy MAAS systems remain in use. The main business risk is limited confidentiality exposure from outdated infrastructure, not a broad emergency response item.

Technical view

CVE-2014-1428 affects Ubuntu MAAS generate_filestorage_key before version 1.9.2. The issue is the use of uuid.uuid1() where an unguessable identifier or token was required, enabling brute-force guessing of filenames. The supplied CVSS v3.0 vector is AV:A/AC:H/PR:H/UI:N/S:U/C:L/I:N/A:N.

Likely exposure

Exposure is likely limited to legacy Ubuntu MAAS deployments older than 1.9.2. The CVSS vector indicates adjacent-network access, high attack complexity, and high privileges are required, with only low confidentiality impact identified.

Exploitation context

The source bundle does not show KEV listing or other cited evidence of active exploitation. The described attack requires guessing file names generated from unsuitable UUID1-based keys, but the provided evidence does not include public exploit status or weaponized details.

Researcher notes

The evidence is sparse: the CVE description identifies generate_filestorage_key and uuid.uuid1(), affected versions before 1.9.2, and low CVSS impact. No CWE, affected CPEs, exploit references, or detailed vendor mitigation text are included in the supplied bundle.

Mitigation direction

  • Upgrade Ubuntu MAAS deployments to version 1.9.2 or later.
  • Check Ubuntu MAAS release notes for vendor-confirmed backports.
  • Retire unsupported legacy MAAS versions where upgrade paths are unavailable.
  • Limit MAAS administrative access to trusted management networks.

Validation and detection

  • Inventory all Ubuntu MAAS instances and installed versions.
  • Confirm no production instance runs MAAS earlier than 1.9.2.
  • Review vendor release notes for the deployed MAAS package build.
  • Check access logs for unusual file-storage resource access.
