Windows OLE Automation Array Remote Code Execution Vulnerability

IdentifiersCVE-2014-6332CWE-190

CVE-2014-6332 is a remote code execution vulnerability in OleAut32.dll within Microsoft Windows OLE/OLE Automation. The flaw is triggered through improper handling of a size value during SAFEARRAY resizing operations, specifically in the SafeArrayDimen/SafeArrayRedim code path as described in the provided content. A crafted web page can trigger an array-redimensioning condition that causes incorrect size validation and unsafe memory handling, leading to arbitrary code execution. The issue affected multiple Windows client and server versions and was commonly exploited through Internet Explorer, including in exploit kits and watering-hole attacks.

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 allows remote attackers to execute arbitrary code in the security context of the current user. If the victim is running with administrative privileges, the attacker can fully compromise the host. In observed campaigns, the vulnerability was used for initial access and malware delivery, including VBScript/PowerShell payload launch, trojan download, and installation of backdoors or banking malware.

Mitigation

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

Until patching is completed, reduce exposure by disabling or restricting active scripting/active content in Internet Explorer in accordance with Microsoft guidance. Additional risk reduction can include limiting use of Internet Explorer on affected systems, restricting access to untrusted websites, and operating users without administrative privileges.

Remediation

Patch, then assume compromise.

Apply Microsoft Security Bulletin MS14-064 / the corresponding Microsoft security update that fixes CVE-2014-6332 in Windows OLE (OleAut32.dll). Ensure affected Windows systems and Internet Explorer environments are updated to the vendor-fixed versions.
