AI-suggested

Organizations should immediately verify the Nokia Single RAN software version in use and plan to upgrade to version 24R1-SR 0.2 MP or later, where the vulnerability is fixed by minimizing the capabilities retained after privilege dropping. Until the upgrade is applied, network administrators should restrict access to the OAM service interfaces through network segmentation, firewall rules, and strict access controls to limit exposure to potentially malicious actors. Monitoring and logging of OAM service activities should be enhanced to detect unusual behavior indicative of exploitation attempts. Additionally, applying host-based security controls such as SELinux or AppArmor profiles tailored to the OAM service can help enforce least privilege and contain potential misuse. Regular audits of capability assignments and privilege dropping mechanisms in network management software are recommended to prevent similar issues. Finally, coordinate with Nokia support for any interim patches or recommended configuration changes.

Description

The Single RAN baseband OAM service is intended to run as an unprivileged service. However, it initially starts with root privileges and assigns certain capabilities before dropping to an unprivileged level. The capabilities retained from the root period are considered extensive after the privilege drop and, in theory, could potentially allow actions beyond the intended scope of the OAM service. These actions could include gaining root privileges, accessing root-owned files, modifying them as the file owner, and then returning them to root ownership. This issue has been corrected starting from release 24R1-SR 0.2 MP and later. Beginning with release 24R1-SR 0.2 MP, the OAM service software capabilities are restricted to the minimum necessary.
