Detailsinfo

A vulnerability classified as critical has been found in Nokia CBIS and NCS (affected version unknown). This affects an unknown functionality of the component Manager API. 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. The summary by CVE is:

The CBIS/NCS Manager API is vulnerable to an authentication bypass. By sending a specially crafted HTTP header, an unauthenticated user can gain unauthorized access to API functions. This flaw allows attackers to reach restricted or sensitive endpoints of the HTTP API without providing any valid credentials. The root cause of this vulnerability lies in a weak verification mechanism within the authentication implementation present in the Nginx Podman container on the CBIS/NCS Manager host machine. The risk can be partially mitigated by restricting access to the management network using external firewall.

The advisory is shared at nokia.com. This vulnerability is uniquely identified as CVE-2023-49564 since 11/27/2023. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 09/21/2025).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
