According to its self-reported version, Cisco IOS-XE Software is affected by an information disclosure vulnerability.
Due to insufficient restrictions in the implementation of the simple network management protocol, a remote, authenticated attacker could retrieve service set identifier (SSID) preshared keys (PSKs) that are configured on the affected device.
Please see the included Cisco BIDs and Cisco Security Advisory for more information.
