Name of the Vulnerable Software and Affected Versions Internet Explorer (affected versions not specified)

Description A remote code execution issue exists due to the way the scripting engine handles objects in memory. This could allow an attacker to execute arbitrary code in the context of the current user. If the current user has administrative rights, an attacker could take control of the affected system, install programs, view, change, or delete data, or create new accounts with full user rights. The issue has been exploited in the wild by groups such as DarkHotel APT and Magnitude EK, introducing a Write-What-Where bug that works in every version of the JScript engine.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
