Detailsinfo

A vulnerability, which was classified as critical, was found in Nokia Airscale ASIKA Single RAN. Affected is some unknown processing. The manipulation with an unknown input leads to a improper authentication vulnerability. CWE is classifying the issue as CWE-287. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.

The weakness was disclosed 06/17/2023. The advisory is available at nokia.com. This vulnerability is traded as CVE-2023-25187 since 02/04/2023. Successful exploitation requires user interaction by the victim. Technical details are unknown but a public exploit is available.

The exploit is shared for download at exploit-db.com. It is declared as proof-of-concept.

Upgrading to version 21B eliminates this vulnerability.

The vulnerability is also documented in the databases at Exploit-DB (51535) and EUVD (EUVD-2023-29151). If you want to get best quality of vulnerability data, you may have to visit VulDB.
