Security readout for executives and security teams
This issue affects Drupal sites using the Hostmaster (Aegir) module in specific older branches. A remote attacker could cause arbitrary PHP code to run through crafted content placed where Apache virtual-host files are written. For organizations hosting multiple Drupal sites through Aegir, this could threaten the management layer and hosted sites. Exposure is likely limited to Drupal multi-site hosting environments using vulnerable Hostmaster/Aegir versions. The supplied affected-product metadata is incomplete, so teams must verify module use and versions directly in their Drupal/Aegir inventory. Prioritize remediation where Aegir manages multiple customer, business, or production Drupal sites. The vulnerability targets the hosting-management layer, so compromise could have broader operational impact than a single site issue. Mitigation focus: Upgrade Hostmaster/Aegir to 6.x-2.4, 7.x-3.0-beta2, or later vendor-supported releases.; Review Drupal advisory and Aegir release notes for environment-specific guidance.; Restrict write access to Apache vhost configuration directories to trusted service accounts..
