Nokia: Security Vulnerabilities
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.

An issue was discovered on NOKIA Airscale ASIKA Single RAN devices before 21B. A mobile network solution internal fault was found in Nokia Single RAN software releases. Certain software processes in the BTS internal software design have unnecessarily high privileges to BTS embedded operating system (OS) resources.

An issue was discovered on NOKIA Airscale ASIKA Single RAN devices before 21B. If/when CSP (as a BTS administrator) removes security hardenings from a Nokia Single RAN BTS baseband unit, a directory path traversal in the Nokia BTS baseband unit diagnostic tool AaShell (which is by default disabled) provides access to the BTS baseband unit internal filesystem from the mobile network solution internal BTS management network.

A mobile network solution internal fault is found in Nokia Web Element Manager before 22 R1, in which an authenticated, unprivileged user can execute administrative functions. Exploitation is not possible from outside of mobile network solution architecture. This means that exploit is not possible from mobile network user UEs, from roaming networks, or from the Internet. Exploitation is possible only from a CSP (Communication Service Provider) mobile network solution internal BTS management network.

In Nokia One-NDS (aka Network Directory Server) through 20.9, some Sudo permissions can be exploited by some users to escalate to root privileges and execute arbitrary commands.

An XXE issue was discovered in Nokia NetAct before 22 FP2211 via an XML document to the Configuration Dashboard page. Input validation and a proper XML parser configuration are missing. For an external attacker, it is very difficult to exploit this, because a few dynamically created parameters such as Jsession-id, a CSRF token, and an Nxsrf token would be needed. The attack can realistically only be performed by an internal user.

An issue was discovered in Nokia NetAct before 22 SP1037. On the Site Configuration Tool tab, attackers can upload a ZIP file which, when processed, exploits Stored XSS. The upload option of the Site Configuration tool does not validate the file contents. The application is in a demilitarised zone behind a perimeter firewall and without exposure to the internet. The attack can only be performed by an internal user.
