Cisco SD-WAN

CVE-2022-20775

Cisco SD-WAN CLI contains a path traversal vulnerability that could allow an authenticated local attacker to gain elevated privileges via improper access controls on commands within the application CLI. A successful exploit could allow the attacker to execute arbitrary commands as the root user.

What this means for your business

  • It affects Cisco SD-WAN. 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 25 February 2026.
  • FIRST's prediction model gives it a 12% chance of attack attempts being seen in the next 30 days, ranking above 95% of all known flaws.

What to do

  1. 1Check whether your company or your suppliers run Cisco SD-WAN.
  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 27 February 2026. 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.
