CVE-2016-4010 Magento CVE debrief

CVE-2016-4010 is a critical Magento vulnerability affecting Community and Enterprise editions before 2.0.6. The issue can allow remote attackers to execute arbitrary PHP code through crafted serialized shopping cart data, which makes internet-facing stores especially high priority for remediation. Magento’s security update for 2.0.6 and the NVD record both point to affected versions through 2.0.5.

Who should care

Magento administrators, e-commerce platform owners, incident responders, and security teams responsible for internet-facing storefronts or custom Magento deployments.

Technical summary

The NVD record classifies the weakness as CWE-74 and assigns CVSS 3.0 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). The vulnerable scope in NVD covers Magento Community and Enterprise versions up to and including 2.0.5. The supplied vendor advisory indicates the fix was delivered in Magento 2.0.6, and the third-party technical writeup describes unauthenticated remote code execution via crafted serialized shopping cart data.

Defensive priority

Immediate. Treat as emergency patching for any exposed or unpatched Magento CE/EE instance running 2.0.5 or earlier.

Recommended defensive actions

  • Upgrade Magento Community or Enterprise to 2.0.6 or later as directed by the vendor advisory.
  • Inventory all Magento deployments, including legacy and custom instances, to confirm no version at or below 2.0.5 remains in service.
  • Prioritize externally reachable storefronts and any systems that process shopping cart or checkout data.
  • Review application and web server logs for signs of unexpected PHP execution or unusual requests against Magento application flows.
  • If patching is delayed, isolate the affected store from public access where feasible and reduce exposure through compensating controls.

Evidence notes

Primary evidence comes from the NVD record and Magento’s security update advisory. NVD lists Magento CE/EE through 2.0.5 as vulnerable and rates the issue CVSS 3.0 9.8. The vendor advisory identifies Magento 2.0.6 as the security update. The MITRE-supplied references include a technical description and exploit-related third-party pages, but this debrief does not rely on exploit mechanics beyond the supplied vulnerability description.
