The image name displays in parentheses, followed by the Cisco IOS Software release number and release name. If the device is running Cisco IOS Software, the system banner displays text similar to Cisco Internetwork Operating System Software or Cisco IOS Software. To determine which Cisco IOS Software release is running on a Cisco product, administrators can log in to the device and issue the show version command to display the system banner. Note: The SSHv2 RSA-based user authentication method is enabled by default however, the public key of a user must be manually imported to enable the functionality. Router#show running-config | begin ip ssh pubkey-chain The following example shows a Cisco IOS router with SSHv2 RSA-based user authentication enabled and configured to authenticate the user test-user: To determine whether RSA-based user authentication is configured for SSHv2 access, use the show running-config | begin ip ssh pubkey-chain command and verify that the ip ssh pubkey-chain command is present and that at least one user is configured. Individual publication links are in Cisco Event Response: September 2015 Semiannual Cisco IOS and IOS XE Software Security Advisory Bundled Publication at the following link:Дevices running a vulnerable version of Cisco IOS and Cisco IOS XE Software are affected if SSHv2 access is configured with RSA-based user authentication and at least one user is configured with a public key. All the advisories address vulnerabilities in Cisco IOS Software and Cisco IOS XE Software. Note: The September 23, 2015, release of the Cisco IOS and IOS XE Software Security Advisory bundled publication includes three Cisco Security Advisories. This advisory is available at the following link: Workarounds for this vulnerability are not available however administrators could temporarily disable RSA-based user authentication to avoid exploitation. This vulnerabilityДЄffects only devices configured for public key authentication method, also known as an RSA-based user authentication feature.Д¬isco has released software updates that address this vulnerability. The attacker must know a valid username configured for Rivest, Shamir, and Adleman (RSA)-based user authentication and the public key configured for that user to exploit this vulnerability. The attacker cannot use this vulnerability to elevate privileges. Depending on the configuration of the user and of the vty line, the attacker may obtain administrative privileges on the system. Successful exploitation could allow the attacker to log in with the privileges of the user or the privileges configured for the Virtual Teletype (VTY) line. Unauthenticated, remote attacker to bypass user authentication.

It is strongly recommended to send this letter with tracking, in case of postal issues.A vulnerability in the SSH version 2 (SSHv2) protocol implementation of Cisco IOS and IOS XE Software could allow an.

When this is received by support, it will then be scanned and attached to the case before TFA is disabled.

Once this step has been completed, a Cisco Meraki Support Specialist will provide you a document which must be signed, notarized, and mailed to Cisco Meraki Headquarters (address found below).

The Support Operations Specialist will request more informationВ about the organization and its contents and settings to verify the validity of the request.

Once in communication with a Cisco Meraki Support Specialist, explain that TFA needs to be disabled for the account and provide the requested documentation.

This permission can be granted only by an organization administrator with Full access.ДЄlternatively, if a second organization administrator with full access does not exist or is otherwise unavailable: The approval must come as a comment on the case.

Email or phone approval is not acceptable for this. A second organization administrator must comment on the case through Dashboard granting approval to disable TFA on the account.It must include the full name of the organization that the account resides in. Open a case by emailing This email mustВ be sent from the email address of the account TFA is to be disabled on.

Please note that 2FAВ removal requestsВ cannot be resolved via our support phone lines.В 2FA disablement needs to be requested and processed by the admin email that needs assistanceВ via a Meraki case for security purposes.
