Windows OLE remote code execution via crafted OLE object

IdentifiersCVE-2014-6352CWE-693

CVE-2014-6352 is a remote code execution vulnerability in Microsoft Windows Object Linking and Embedding (OLE) affecting Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold and R2, and Windows RT Gold and 8.1. According to the provided content, the flaw allows remote attackers to execute arbitrary code via a crafted OLE object and was exploited in the wild in October 2014 using a crafted PowerPoint document. The supporting context further states that MS14-064 addressed CVE-2014-6352 and that the issue was considered an insufficient fix for CVE-2014-4114, the Sandworm-associated OLE package manager vulnerability. Based on the supplied information, the vulnerability is triggered when a victim opens a malicious Office document containing the crafted OLE content, leading to attacker-controlled code execution on the target system.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation results in remote code execution on the victim system. In practical attack chains described in the content, malicious PowerPoint documents exploiting CVE-2014-6352 were used to execute malware payloads after document opening. Because the flaw was exploited in the wild as a zero-day, it enabled real-world initial compromise of targeted users through document-based delivery.

Mitigation

If you can’t patch tonight, do this now.

Until patching is completed, reduce exposure by blocking or tightly controlling delivery of untrusted Office documents, especially PowerPoint files containing embedded OLE content; use Protected View and attachment sandboxing where available; and restrict users from opening unsolicited documents from email or web downloads. The supplied reporting also indicates that basic patching hygiene and user awareness against social-engineering-based document lures would mitigate observed exploitation activity.

Remediation

Patch, then assume compromise.

Apply Microsoft security update MS14-064, which fixes CVE-2014-6352 in Windows OLE. The provided content identifies MS14-064 as the bulletin that remediates this vulnerability. Systems running affected Windows versions should be updated to the vendor-fixed builds.
