Remote Code Execution Vulnerability Disclosed

Researchers at Telspace Systems have advised they have found a Zero Day exploit, but no fix is yet available. The release date has been estimated to be in the July 2018 Patch Tuesday, however we will let you know when a fix is announced.

The issue lies in Microsoft’s ECMAScript standard – its JScript component used in Internet Explorer. In this case, JScript is implemented as an active scripting engine.

The flaw could allow code execution within a sandboxed environment which usually is protected from access. An attacker can then leverage the vulnerability to execute code under the context of the current process.
