CVE-2016-6367

A vulnerability in the command-line interface (CLI) parser of Cisco ASA software could allow an authenticated, local attacker to create a denial-of-service (DoS) condition or potentially execute code.

What this means for your business

  • It affects Cisco Adaptive Security Appliance (ASA). It matters if your company, or a supplier that handles your data, runs it.
  • Attackers are already using it. CISA added it to its list of flaws used in real attacks on 24 May 2022.
  • FIRST's prediction model gives it a 23% chance of attack attempts being seen in the next 30 days, ranking above 97% of all known flaws.

What to do

  1. 1Check whether your company or your suppliers run Cisco Adaptive Security Appliance (ASA).
  2. 2If you do, follow CISA's required action below. No patch reference has been published yet.
  3. 3Treat it as urgent. US federal agencies must fix it by 14 June 2022. That deadline does not apply to private companies, but it shows how seriously CISA takes it.
  4. 4Because attackers have used it, check the affected systems for signs of a break-in, not only for the update.
