Siemens RUGGEDCOM APE 1808

CVSS 9.1 CRITICAL

Remediations

  • Configure the RADIUS server to require the presence of a Message-Authenticator attribute in all Access-Request packets from RADIUS client devices that support it
  • Customers can resolve this issue by configuring the in-use SSH profile to contain at least one cipher and at least one MAC algorithm, which removes support for CHACHA20-POLY1305 and all Encrypt-then-MAC algorithms available (ciphers with -etm in the name) in PAN-OS software. See Palo Alto Networks' upstream documentation https://security.paloaltonetworks.com/CVE-2023-48795 for additional guidance.
  • Restrict access to the networks where RADIUS messages are exchanged (e.g., send RADIUS traffic via management network or a dedicated VLAN)
  • Upgrade Palo Alto Networks Virtual NGFW V11.1.4-h1. Contact customer support to receive patch and update information
  • Exposure can be reduced by limiting access to the management interface to trusted internal IP addresses as described in Palo Alto Networks' Security Advisory
