A vulnerability in the web-based management interface of the Wireless LAN Controller feature of Cisco IOS XE Software could allow an authenticated, remote attacker with a lobby ambassador user account to perform a command injection attack against an affected device.
This vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by sending crafted input to the web-based management interface. A successful exploit could allow the attacker to execute arbitrary Cisco IOS XE Software CLI commands with privilege level 15.
Note: This vulnerability is exploitable only if the attacker obtains the credentials for a lobby ambassador account. This account is not configured by default.

Detection & IOCsextracted from sources · hover to see the quote
- →Detect command injection attempts via the Cisco IOS XE web-based management interface (Wireless LAN Controller feature) originating from authenticated lobby ambassador accounts — look for crafted/unexpected input in web UI requests that may contain CLI command syntax ↗
- →Alert on privilege escalation to privilege level 15 on Cisco IOS XE devices initiated through the web-based management interface, especially when the session is associated with a lobby ambassador account ↗
- →Monitor for the existence or unexpected activation of lobby ambassador accounts on Cisco IOS XE devices — this account type is not present by default and its presence may indicate pre-exploitation staging ↗
- →Track Cisco bug ID CSCwk27168 for patch status; use this identifier to correlate vendor advisories and affected software version lists for IOS XE Wireless LAN Controller deployments ↗
- ·The vulnerability only exists when the Wireless LAN Controller feature is active on Cisco IOS XE and a lobby ambassador account has been configured — devices without this account are not exploitable ↗
- ·There are no workarounds available; the only remediation is applying Cisco's software updates ↗
