Impact

The CVSS vector (AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:N/A:N) indicates network-accessible exploitation with high attack complexity and requiring user interaction, which moderates real-world risk despite the high confidentiality impact. The CISA SSVC assessment reports no known exploitation, indicating this is not yet actively weaponized in the wild. Attack automatable status is marked as 'no,' meaning reliable exploitation requires manual effort and precise network positioning. However, the information disclosure impact is significant—compromised configurations expose API keys, routing protocols, and device credentials to attackers in-transit. The combination of no active KEV entries, high attack complexity, and lack of public proof-of-concept code suggests this is a real but not immediately critical threat; however, organizations using Meraki-managed IOS XE devices in high-risk network environments should prioritize patching to prevent credential compromise and lateral movement.

Exploit ScenarioDerived

An attacker positioned on the network path between a Cisco IOS XE-based Meraki-managed device and the Cisco Meraki Dashboard—such as a compromised gateway router or via ARP spoofing on a shared network segment—passively captures configuration upload traffic. The attacker extracts plaintext or weakly-encrypted API credentials, SNMPv2 community strings, and network topology information from the intercepted packets. Using these credentials, the attacker gains unauthorized access to the device's management interface or the broader network managed by those credentials, enabling reconnaissance for lateral movement or persistent access.

AnalysisAIv1 – Mar 25, 2026

Cisco Meraki devices running vulnerable IOS XE Software transmit configuration data over unencrypted channels, enabling remote attackers to intercept sensitive device information through on-path attacks. The vulnerability requires user interaction and network proximity but carries no patch availability, leaving affected organizations exposed until remediation is implemented. This affects both Cisco and Apple products integrating the vulnerable software.

Earlier versions of this analysis (1)
v1 Mar 25, 2026 - 16:16 CVSS 6.1

A remote, unauthenticated attacker can view sensitive device configuration information in Cisco IOS XE Software for Cisco Meraki by conducting an on-path attack between the affected device and the Cisco Meraki Dashboard. The vulnerability stems from device configuration uploads being performed over an insecure tunnel, allowing interception and disclosure of confidential data. No active exploitation has been reported in public KEV databases, and the CVSS 6.1 score reflects high confidentiality impact but requires high attack complexity and user interaction.

RemediationAI

Upgrade affected Cisco IOS XE Software to a patched version released after the advisory date, following the specific fixed versions listed in the Cisco Security Advisory at https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe_infodis-6J847uEB. As an interim mitigation, restrict network access to the Meraki Dashboard by implementing network segmentation and firewall rules that limit device-to-dashboard communication to trusted, encrypted channels only; additionally, enforce TLS 1.2 or higher for all Meraki management connections and monitor for suspicious on-path traffic patterns using network intrusion detection systems tuned to detect cleartext configuration transmissions. For organizations unable to immediately patch, consider disabling automatic configuration uploads until the device can be updated.

Technical ContextAI · show details

This vulnerability is rooted in CWE-319 (Cleartext Transmission of Sensitive Information), where Cisco IOS XE Software (CPE: cpe:2.3:a:cisco:cisco_ios_xe_software) fails to encrypt configuration upload traffic to the Cisco Meraki Dashboard management interface. The affected technology involves the Meraki cloud management protocol used by Cisco IOS XE-based devices to synchronize device configurations. Rather than using encrypted tunnels (TLS/SSL) for all sensitive data in transit, the device sends configuration data over an insecure channel, permitting on-path attackers to passively intercept and read plaintext or weakly-protected configuration payloads containing credentials, network topology, and operational parameters.
