CVE-2016-0189

Microsoft Internet Explorer

The Microsoft JScript nd VBScript engines, as used in Internet Explorer and other products, allow attackers to execute remote code or cause a denial of service (memory corruption) via a crafted web site.

Exploitation status

  • CISA has confirmed this is being exploited in the wild. That is an observation of real attacks, not a prediction.
  • It is known to have been used in ransomware campaigns.
  • US federal civilian agencies are required to remediate it by 2022-04-18. That deadline does not bind private companies, but it is a reasonable benchmark for how urgently CISA views it.

Required action

Apply updates per vendor instructions.
