CVE-2011-3007
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe myCIOScn ActiveX control (myCIOScn.dll) in McAfee SaaS Endpoint Protection 5.2.1 and earlier allows remote attackers to write to arbitrary files by specifying an arbitrary filename in the MyCioScan.Scan.ReportFile parameter, as demonstrated by injecting script into a log file and executing arbitrary code using the MyCioScan.Scan.Start method.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check McAfee SaaS Endpoint Protection versionLook in the Windows registry under HKLM\SOFTWARE\Network Associates\ePolicy Orchestrator\Application Modules\Installed or check Program Files\McAfee\SaaS\Endpoint\Protection for version informationAffected if The installed version is 5.2.1 or earlier
-
Verify presence of vulnerable ActiveX componentSearch for myCIOScn.dll in the McAfee installation directory, typically under Program Files\McAfee\SaaS\Endpoint\ or Program Files\McAfee\Common Files\Affected if The file myCIOScn.dll exists on the system
-
Confirm ActiveX control is registeredCheck Windows registry under HKCR\CLSID\ for the CLSID associated with myCIOScn ActiveX control, or look in HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing\ for the componentAffected if The ActiveX control is registered and present in the Windows registry
-
Check if control is enabled in Internet ExplorerOpen Internet Explorer, go to Tools > Internet Options > Security > Custom Level, or check registry under HKLM\SOFTWARE\Policies\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains for ActiveX control settingsAffected if The ActiveX control is allowed to run or no kill bit has been set for the CLSID
A system is affected if McAfee SaaS Endpoint Protection version 5.2.1 or earlier is installed AND the myCIOScn ActiveX control is present and registered on the system.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade McAfee SaaS Endpoint Protection to a version newer than 5.2.1, or disable the vulnerable myCIOScn ActiveX control in Internet Explorer as a compensating control.
