CVE-2006-2492 is a malformed object pointer vulnerability in Microsoft Word. CISA added it to the Known Exploited Vulnerabilities catalogue on 8 June 2022, which means attackers have used it in real attacks. Microsoft Word and Microsoft Works Suites contain a malformed object pointer which allows attackers to execute code.
What the vulnerability means in practice
This flaw matters because Microsoft Word is a trusted document format parser, and malformed object pointer bugs can let a crafted file trigger code execution when the document is opened. In a productivity suite, that turns routine document handling into an attack path.
Word and related office components are often exposed through email, downloads, shared drives and collaboration platforms, so the vulnerable surface is not just the application itself but the way users receive documents. That makes the issue especially dangerous when the product is widely used inside an organisation.
How organisations assess exposure
Exposure checks start with an accurate inventory of every system that can open the affected Microsoft Office components, including desktops, virtual desktops and shared application servers. Teams should then compare that inventory against vendor advisories and the NIST National Vulnerability Database and the CVE Program record to confirm the exact vulnerability identity and tracking details.
For a document-processing flaw like this, internet exposure is only part of the picture. Internal email gateways, file shares, help-desk attachments and browser download paths can all deliver a weaponised file, so exposure analysis should include every route by which an untrusted document can reach a user.
Remediation and compensating controls
The safest response is to apply the vendor’s fix as soon as practical, then verify that the vulnerable software is no longer reachable in the environment. When patching is delayed, organisations should reduce document risk by limiting who can open untrusted files, tightening attachment filtering, and isolating high-risk document handling where feasible.
Compensating controls are most effective when they reduce both delivery and execution opportunities. Strong application hardening, least-privilege user sessions, and attachment inspection can all help limit the blast radius if a malicious file is introduced before remediation is complete.
Detection and post-exploitation review
If exploitation is suspected, defenders should look for unusual Word launches, child processes spawned from Office applications, suspicious script or shell activity, and unexpected network connections following document open events. Review email, proxy, endpoint and EDR telemetry together, because the initial trigger may be a document but the compromise often continues through secondary payloads.
After patching, perform a compromise review rather than assuming the absence of alerts means the system was clean. A successful document exploit can leave behind persistence, dropped binaries, changed startup locations or stolen credentials that remain useful even after the original vulnerability is fixed.
Risk and Threat Considerations
Document parser vulnerabilities are attractive because they exploit a normal business behaviour, opening files, and they can deliver code execution before users realise anything is wrong. That makes them a common initial access mechanism for malware delivery, lateral movement and follow-on credential theft.
Failure mechanism: A malformed object pointer corrupts program logic during file parsing, allowing attacker-controlled content in a Word document to execute code in the user context.
Impact: Successful exploitation can lead to endpoint compromise, payload delivery, data theft and expansion into adjacent systems where the user has access.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
CIS Controls v8, NIST SP 800-53 Rev 5 and OWASP ASVS set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| CIS Controls v8 | CIS-7 — Continuous Vulnerability Management | Malware-exploited CVEs require prioritised identification and remediation. |
| Recommendation — Prioritise and remediate exploited Word vulnerabilities across the asset estate. | ||
| NIST SP 800-53 Rev 5 | SI-2 — Flaw Remediation | This CVE is a software flaw that needs timely remediation and verification. |
| SI-3 — Malicious Code Protection | Weaponised documents are a malicious-code delivery path that this control helps constrain. | |
| AU-6 — Audit Review, Analysis, and Reporting | Post-exploit review depends on correlating endpoint, email, and process telemetry. | |
| Recommendation — Track, patch, and verify remediation for affected Word installations. Inspect and block malicious document payloads before they execute. Correlate logs to confirm whether Office documents triggered compromise. | ||
| OWASP ASVS | V16 — Security Logging and Error Handling | Detection and forensic review depend on logs that capture suspicious execution chains. |
| Recommendation — Log suspicious document-triggered execution paths for investigation. | ||
Practitioner Guidance
Why practitioners should care: Treat document-based code execution as an endpoint and identity-adjacent event, not just a desktop software issue. If the exploited user has access to sensitive shares, email, admin tools or cached sessions, the downstream impact can be much broader than the initial workstation compromise.
What to watch for: Prioritise systems that regularly process externally sourced documents, especially where users work with macros, embedded objects or legacy Office formats. Those environments deserve faster patching, tighter attachment controls and stronger monitoring for post-open behaviour.
