CVE-2022-20775

What the flaw is

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.

Description as published by CISA. We have not independently reproduced it.

What CISA requires

Please adhere to CISA’s guidelines to assess exposure and mitigate risks associated with Cisco SD-WAN devices as outlines in CISA’s Emergency Directive 26-03 (URL listed below in Notes) and CISA’s “Hunt & Hardening Guidance for Cisco SD-WAN Devices (URL listed below in Notes). Adhere to the applicable BOD 22-01 guidance for cloud services or discontinue use of the product if mitigations are not available.

This deadline is binding on US federal civilian agencies under BOD 22-01. It is not a legal deadline for anyone else, but it is a useful urgency signal — CISA sets it by how actively the flaw is being used, not by CVSS.
