An issue was discovered on NOKIA Airscale ASIKA Single RAN devices before 21B. Nokia Single RAN commissioning procedures do not change (factory-time installed) default SSH public/private key values that are specific to a network operator. As a result, the CSP internal BTS network SSH server (disabled by default) continues to apply the default SSH public/private key values. These keys don't give access to BTS, because service user authentication is username/password-based on top of SSH. Nokia factory installed default SSH keys are meant to be changed from operator-specific values during the BTS deployment commissioning phase. However, before the 21B release, BTS commissioning manuals did not provide instructions to change default SSH keys (to BTS operator-specific values). This leads to a possibility for malicious operations staff (inside a CSP network) to attempt MITM exploitation of BTS service user access, during the moments that SSH is enabled for Nokia service personnel to perform troubleshooting activities.
This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 6.3, requiring local system access to exploit but requires specific conditions to be met though user interaction is required . The vulnerability impacts confidentiality (data exposure), integrity (unauthorized modifications), and availability (service disruption) for affected systems. Impacting 2 products from nokia, from nokia organizations running these solutions should prioritize assessment and patching.
Reported in 2023, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For nokia's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
