CVE-2023-25727 Festo Didactic SE CVE debrief

Who should care

Administrators and operators of Festo Didactic SE MES PC environments, especially where phpMyAdmin or a bundled XAMPP-based workflow is exposed to authenticated users. Security teams should also review any environment where users can upload .sql files through a drag-and-drop import interface.

Technical summary

The source description states that phpMyAdmin before 4.9.11 and 5.x before 5.2.1 allows an authenticated user to trigger XSS by uploading a crafted .sql file through the drag-and-drop interface. The supplied CSAF advisory links this CVE to Festo Didactic SE MES PC and identifies a vendor remediation path that replaces XAMPP with Factory Control Panel. The supplied CVSS vector is CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N, reflecting network reachability, required authentication, and user interaction.

Defensive priority

Medium. Prioritize if the affected import feature is reachable by multiple authenticated users or by privileged operators, since successful exploitation can hijack browser sessions or alter displayed content for other users.

Recommended defensive actions

• Update phpMyAdmin to 4.9.11 or later in the 4.9 line, or 5.2.1 or later in the 5.x line, wherever it is deployed.
• If the vulnerability applies through Festo MES PC, obtain and deploy the current Factory Control Panel version from Festo support as described in the advisory remediation.
• Restrict access to authenticated import and drag-and-drop upload features to the smallest possible user set.
• Review account privileges for users who can upload .sql files and enforce least privilege and strong authentication controls.
• Audit affected systems for unexpected import activity or browser-side anomalies tied to authenticated sessions.
• Use the vendor and CISA advisory references to confirm which installed component version is actually present before planning remediation.

Evidence notes

The supplied source corpus is a CISA CSAF advisory (ICSA-26-027-02) published on 2024-02-27, with later administrative revisions including a 2026 republication date; those later timestamps are not the CVE’s original publication date. The advisory text explicitly describes the phpMyAdmin .sql drag-and-drop XSS condition and lists a remediation that replaces XAMPP with Factory Control Panel for MES PCs. The corpus also provides the CVSS vector CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N, and no KEV or active-threat enrichment is supplied.
