Cisco | Cisco IOS XE Web UI

CVE-2023-20273

Cisco IOS XE Web UI Command Injection Vulnerability: Cisco IOS XE contains a command injection vulnerability in the web user interface. When chained with CVE-2023-20198, the attacker can leverage the new local user to elevate privilege to root and write the implant to the file system. Cisco identified CVE-2023-20273 as the vulnerability exploited to deploy the implant. CVE-2021-1435, previously associated with the exploitation events, is no longer believed to be related to this activity.

Related CWE: CWE-78
