Cisco SD-WAN Path Traversal Vulnerability
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.
A local attacker, with a low-privilege account, can achieve full data confidentiality loss, arbitrary modification of data, complete denial of service or system unavailability. Federal agencies are required to remediate by 2026-02-27 under CISA BOD 22-01.
This is a Software Vulnerability (CWE-25) (CWE-25) vulnerability in Cisco SD-WAN. A vulnerability in the CLI of Cisco SD-WAN Software could allow an authenticated, local attacker to gain elevated privileges. This vulnerability is due to improper access controls on commands within the application CLI. An attacker could exploit this vulnerability by running a maliciously crafted command on the application CLI. A successful exploit could allow the attacker to execute arbitrary commands as the root user. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sd-wan-priv-E6e8tEdF Exploitation requires local access, low attack complexity, a low-privilege authenticated account, and no user interaction required.
Probably yes if any of these apply:
