A security regression (CVE-2006-5051) was discovered in OpenSSH's server (sshd). There is a race condition which can lead sshd to handle some signals in an unsafe manner. An unauthenticated, remote attacker may be able to trigger it by failing to authenticate within a set time period.

AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C

A fundamental design flaw within the RADIUS protocol has been proven to be exploitable, compromising the integrity in the RADIUS Access-Request process. The attack allows a malicious user to modify packets in a way that would be indistinguishable to a RADIUS client or server. To be successful, the attacker must have the ability to inject themselves between the client and server.

Source: FortiGuard

Remedy

Disable the use of RADIUS/UDP and RADIUS/TCP - instead RADIUS/TLS or RADIUS/DTLS should be used.

Remedy

TBD

Remedy

The best way to address this issue is by using encrypted and authenticated channels that offer modern cryptographic security guarantees. Configure an alternate authentication mechanism if you are using RADIUS with a CHAP or PAP authentication protocol. PAN-OS provides the following alternate RADIUS authentication mechanisms: PEAP-MSCHAPv2 (default), PEAP with GTC, and EAP-TTLS with PAP. For more information, please see https://docs.paloaltonetworks.com/pan-os/11-1/pan-os-admin/authentication/configure-radius-authentication. In addition, instead of using RADIUS, you can configure an alternate authentication mechanism using one of the options described here: https://docs.paloaltonetworks.com/pan-os/11-1/pan-os-admin/authentication. If you are a Prisma Access customer using a RADIUS configuration with PAP or CHAP in your profile and have not applied one of the changes described above, please reach out to TAC/CS to schedule an upgrade window. PAN-OS 9.1.19, PAN-OS 10.1.14, PAN-OS 10.2.10, PAN-OS 11.0.7, PAN-OS 11.1.3, and all later PAN-OS versions add a new feature to enforce an authentication check in RADIUS. This new feature is disabled by default to match the existing behavior. To enable this feature, run the following commands: > set auth radius-require-msg-authentic yes To confirm that the setting was correctly enabled, run the following command: > show auth radius-require-msg-authentic If set correctly, the response will say "yes". This setting is persistent across reboots. No ‘commit’ is required for this to take effect. Please note that this feature requires that the RADIUS server has been updated to support the new protocol changes, as detailed in https://kb.cert.org/vuls/id/456537. If your RADIUS authentication breaks when radius-require-msg-authentic is set to yes, please work with your RADIUS server vendor for support with the RADIUS server upgrade process.
