CVE-2014-6352 is a code injection vulnerability in Microsoft Windows. CISA added it to the Known Exploited Vulnerabilities catalogue on 25 February 2022, which means attackers have used it in real attacks. Microsoft Windows allow remote attackers to execute arbitrary code via a crafted OLE object.
What Makes This Vulnerability Dangerous
CVE-2014-6352 is dangerous because a crafted OLE object can let a remote attacker trigger arbitrary code execution inside Microsoft Windows. That turns a file- or document-handling flaw into a direct execution path, which is especially concerning when the object is opened in a trusted desktop workflow.
For exposure review, the practical question is not just whether Windows is present, but whether users or services can receive and process untrusted OLE content. In a CVE context, the authoritative record remains the CVE Program entry and the NIST National Vulnerability Database, which are the right places to confirm record details and remediation references.
How Organisations Check Exposure
Exposure checks start with asset inventory, product scope, and where untrusted OLE content can reach endpoints. Organisations should identify Windows systems that still accept this file path, then compare them with vendor guidance and the CISA KEV catalogue entry referenced in the primary definition.
Prioritisation improves when vulnerability management is tied to real exploitability rather than abstract severity alone. NHIMG’s Vulnerability Management Guide is useful here because it frames scanning, asset scope, KEV-driven prioritisation, exceptions and verification as one workflow rather than separate activities.
For Windows environments, the exposure review should also include any document, email, browser, or file-transfer path that can deliver a crafted OLE object to an endpoint. If a system can ingest hostile content, the vulnerability is not just theoretical, it is part of the reachable attack surface.
Remediation and Compensating Controls
Remediation should follow the vendor advisory for version and patch specifics, but the operational goal is to eliminate the code-injection path as quickly as possible. Where patching is delayed, reduce exposure by constraining how untrusted files are handled, limiting document provenance, and narrowing the systems that can process risky content.
Compensating controls matter because code injection often succeeds through normal user workflows. Mail filtering, attachment handling rules, hardened document viewers, and least-privilege endpoint configuration can all reduce the chance that a malicious object reaches a vulnerable execution context.
When the issue is being tracked alongside broader Windows exploitation patterns, the State of NHI & AI Agent Breach Report 2026 is relevant as a reminder that real-world intrusions often chain initial execution with follow-on credential theft and lateral movement.
Detection and Post-Exploitation Review
Detection should focus on whether OLE content was opened, whether unusual child processes followed document handling, and whether the endpoint shows evidence of unexpected code execution soon after file ingestion. That sequence is more important than the exploit name alone, because a successful attack may leave behind only process, file, or network traces.
After patching, organisations should review for post-compromise activity, not just vulnerability closure. If the flaw was exploited, the incident review should check for persistence, suspicious script or binary launches, and any signs that attacker-controlled code used the initial execution foothold to expand access.
For hunting and triage, the broader attack pattern is similar to other remote code execution cases documented in NHIMG material such as ASP.NET machine key attacks 2025, where a trusted mechanism was turned into code execution through a malicious payload path.
Risk and Threat Considerations
This vulnerability matters because document- and object-based code execution can give attackers an initial foothold on endpoints that users consider routine and safe. Once that foothold exists, the real risk is not only execution, but the follow-on actions that arbitrary code can enable inside a Windows environment.
Failure mechanism: A crafted OLE object is processed by a vulnerable Windows component, causing attacker-controlled code to run in the context of the recipient process or user.
Impact: The attacker can gain execution on the host, stage additional payloads, and potentially move toward credential theft, persistence, or broader compromise.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
NIST SP 800-53 Rev 5, CIS Controls v8 and OWASP ASVS set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST SP 800-53 Rev 5 | SI-3 — Malicious Code Protection | CVE-2014-6352 can deliver code via crafted content, making malicious code controls directly relevant. |
| SI-2 — Flaw Remediation | The term is a live vulnerability that requires patching and remediation tracking. | |
| AC-6 — Least Privilege | Code execution impact is reduced when exposed endpoints and users have limited authority. | |
| Recommendation — Apply SI-3 to block, scan, and quarantine hostile files before they reach vulnerable Windows hosts. Use SI-2 to track patch status, exceptions, and validation for affected Windows assets. Enforce AC-6 to limit what compromised Windows processes and users can do after exploitation. | ||
| CIS Controls v8 | CIS-7 — Continuous Vulnerability Management | The term is a KEV-listed exploited vulnerability that fits continuous vulnerability prioritisation. |
| Recommendation — Prioritise KEV-listed Windows exposure in CIS-7 scanning, remediation, and verification cycles. | ||
| OWASP ASVS | V5 — File Handling | The exploit path uses crafted object content, which aligns with secure file handling concerns. |
| Recommendation — Review file-handling controls to ensure hostile document content cannot trigger unsafe execution. | ||
Practitioner Guidance
Why practitioners should care: Treat this as a reachable execution problem, not just a patching ticket. The key operational question is where untrusted objects can enter the environment and which endpoints still have the ability to process them.
What to watch for: Prioritise systems that receive external documents, archive content, or email attachments, because those are the workflows most likely to turn a crafted OLE object into an exploit path. Validate remediation by checking both patch state and the absence of risky intake paths.
