CVE-2021-36025: Magento Commerce Customer Edition Improper Input Validation Could Lead To Remote Code Execution

Magento Commerce versions 2.4.2 (and earlier), 2.4.2-p1 (and earlier) and 2.3.7 (and earlier) are affected by an improper input validation vulnerability while saving a customer's details with a specially crafted file. An authenticated attacker with admin privileges can leverage this vulnerability to achieve remote code execution.

Security readout for executives and security teams

Plain-English summary

This is a critical Magento Commerce issue where an administrator could trigger remote code execution by saving customer details with a specially crafted file. The attacker needs admin privileges, which narrows exposure, but successful exploitation could compromise the server and business data.

Executive priority

Treat as urgent for any internet-facing or business-critical Magento Commerce environment. The privilege requirement reduces likelihood, but remote code execution on an ecommerce platform can lead to outage, data theft, and transaction integrity risk.

Technical view

CVE-2021-36025 is an improper input validation flaw in Magento Commerce customer-detail handling. A network-accessible, authenticated admin attacker can use a crafted file during customer detail saving to achieve remote code execution. CVSS 3.1 score is 9.1 with high confidentiality, integrity, and availability impact.

Likely exposure

Organizations running Adobe Magento Commerce 2.4.2, 2.4.2-p1, 2.3.7, or earlier branches should assume potential exposure until version and patch state are verified.

Exploitation context

The provided sources do not show CISA KEV listing or active exploitation evidence. Exploitation requires authenticated admin privileges, so compromised, shared, or overprivileged admin accounts materially increase risk.

Researcher notes

Evidence is limited to CVE metadata and Adobe advisory references. Do not assume unauthenticated exploitation, public exploit availability, or exact fixed versions from this bundle alone. Focus validation on affected version discovery, admin access exposure, and Adobe bulletin alignment.

Mitigation direction

  • Review Adobe APSB21-64 and apply the vendor-published security update guidance.
  • Inventory Magento Commerce instances and identify versions at or below the affected releases.
  • Restrict Magento admin access to trusted networks and required administrators only.
  • Review admin accounts, remove unnecessary privileges, and enforce strong authentication.
  • Monitor Adobe guidance for any additional mitigation or patch instructions.

Validation and detection

  • Confirm each Magento Commerce instance version and patch level against APSB21-64.
  • Verify no production instance remains on affected 2.4.2, 2.4.2-p1, 2.3.7, or earlier versions.
  • Review admin account activity around customer-detail changes and file handling.
  • Check logs for unexpected admin sessions, new admin users, or suspicious customer record updates.
