CVE-2022-20818

CVE-2022-20818 describes multiple privilege escalation vulnerabilities in the CLI of Cisco SD-WAN Software. These flaws, caused by improper access controls, allow an authenticated, local attacker to execute arbitrary commands as the root user. With a CVSS score of 7.8 (High), exploitation requires local access but has low attack complexity and can lead to complete compromise of confidentiality, integrity, and availability. There is no evidence of active exploitation, publicly available exploit code, or inclusion in CISA's KEV catalog, though it has received some community discussion and media coverage.
