CVE-2023-6729 — Nokia SR OS routers security vulnerability

High CVSS 7.3

Nokia SR OS routers allow read-write access to the entire file system via SFTP or SCP for users configured with "access console." Consequently, a low privilege authenticated user with "access console" can read or replace the router configuration file as well as other files stored in the Compact Flash or SD card without using CLI commands. This type of attack can lead to a compromise or denial of service of the router after the system is rebooted.

Matched remediation archetype

Privilege escalation and unsafe privilege management

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map service accounts, operating-system identities, roles, capabilities, impersonation, set-user transitions, and administrative helper paths.
  • Determine whether untrusted users or lower-privilege processes can reach the affected transition or modify inputs it trusts.
  • Review file, socket, registry, device, job, container, and cloud-role permissions used before and after privilege changes.

Remediate safely

  • Apply the supported fix and redesign privileged operations as a minimal, authenticated, allowlisted interface.
  • Drop privileges before processing untrusted input, verify the drop succeeds, and remove unnecessary roles, capabilities, and write permissions.
  • Validate ownership and permissions at time of use and add explicit lower-to-higher privilege boundary tests.
