Nokia Single Ran

Nokia Single RAN baseband software versions earlier than 24R1-SR 2.1 MP contain a SOAP message input validation flaw, which in theory could potentially be used for causing resource exhaustion in the Single RAN baseband OAM service. No practical exploit has been detected for this flaw. However, the issue has been corrected starting from release 24R1-SR 2.1 MP by adding sufficient input validation for received SOAP requests, effectively mitigating the reported issue.

The Nokia Single RAN baseband software earlier than 23R2-SR 1.0 MP can be made to reveal the exact software release version by sending a specific HTTP POST request through the Mobile Network Operator (MNO) internal RAN management network.

Nokia Single RAN baseband software earlier than 24R1-SR 1.0 MP contains administrative shell input validation fault, which authenticated admin user can, in theory, potentially use for injecting arbitrary commands for unprivileged baseband OAM service process execution via special characters added to baseband internal COMA_config.xml file. This issue has been corrected starting from release 24R1-SR 1.0 MP and later, by adding proper input validation to OAM service process which prevents injecting special characters via baseband internal COMA_config.xml file.

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.

Sending a crafted SOAP "provision" operation message PlanId field within the Mobile Network Operator (MNO) internal Radio Access Network (RAN) management network can cause path traversal issue in Nokia Single RAN baseband software with versions earlier than release 24R1-SR 1.0 MP. This issue has been corrected to release 24R1-SR 1.0 MP and later. Beginning with release 24R1-SR 1.0 MP, the OAM service software performed PlanId field input validations mitigate the reported path traversal issue.
