CVE-2020-24406: Document root path disclosure on Maintenance page

When in maintenance mode, Magento version 2.4.0 and 2.3.4 (and earlier) are affected by an information disclosure vulnerability that could expose the installation path during build deployments. This information could be helpful to attackers if they are able to identify other exploitable vulnerabilities in the environment.

Security readout for executives and security teams

Plain-English summary

CVE-2020-24406 is a low-severity Magento information disclosure issue. During build deployments, a site in maintenance mode may reveal its installation path. That path alone is not a compromise, but it can help attackers understand the environment if another vulnerability is present.

Executive priority

Treat this as a hygiene and hardening item, not an emergency. Prioritize remediation during normal patch cycles, especially for internet-facing Magento stores or environments with frequent public maintenance windows.

Technical view

Magento Commerce 2.4.0, 2.3.4, and earlier are reported affected. The issue is CWE-200 information disclosure with CVSS 3.1 score 3.7: network reachable, high attack complexity, no privileges, no user interaction, low confidentiality impact only.

Likely exposure

Exposure is most likely on Magento Commerce sites that enter publicly reachable maintenance mode during build deployments. The bundle does not identify affected configurations beyond versions 2.4.0, 2.3.4, and earlier.

Exploitation context

The source bundle does not report active exploitation, and CISA KEV status is false. The disclosed document root path is mainly useful for reconnaissance and would usually matter more when combined with another exploitable weakness.

Researcher notes

Evidence is limited to the CVE record and Adobe advisory reference. The bundle names no exploit, no specific fixed version, and no standalone workaround. Analysis should stay scoped to path disclosure during maintenance-mode build deployments.

Mitigation direction

  • Review Adobe APSB20-59 and apply applicable Magento security updates.
  • Inventory Magento Commerce instances at 2.4.0, 2.3.4, or earlier.
  • Reduce public exposure of maintenance pages during deployment windows where feasible.
  • Check vendor guidance before assuming a standalone workaround exists.

Validation and detection

  • Confirm Magento Commerce versions across production and staging environments.
  • Review deployment workflows for public maintenance mode exposure.
  • Inspect maintenance page behavior defensively for installation path disclosure.
  • Check vulnerability management records for APSB20-59 remediation status.
