Vulnerabilities

Nokia SR OS routers allow read-write access to the entire file system via SFTP or SCP for users configured with "access console." Consequently, a low privilege authenticated user with "access console" can read or replace the router configuration file as well as other files stored in the Compact Flash or SD card without using CLI commands. This type of attack can lead to a compromise or denial of service of the router after the system is rebooted.

Nokia SR OS bof.cfg file encryption is vulnerable to a brute force attack. This weakness allows an attacker in possession of the encrypted file to decrypt the bof.cfg file and obtain the BOF configuration content.

Chunghwa Telecom NOKIA G-040W-Q Firewall function has a vulnerability of input validation for ICMP redirect messages. An unauthenticated remote attacker can exploit this vulnerability by sending a crafted package to modify the network routing table, resulting in a denial of service or sensitive information leaking.

Chunghwa Telecom NOKIA G-040W-Q has a vulnerability of weak password requirements. A remote attacker with regular user privilege can easily infer the administrator password from system information after logging system, resulting in admin access and performing arbitrary system operations or disrupt service.

Chunghwa Telecom NOKIA G-040W-Q has a vulnerability of insufficient filtering for user input. A remote attacker with administrator privilege can exploit this vulnerability to perform a Command Injection attack to execute arbitrary commands, disrupt the system or terminate services.

Chunghwa Telecom NOKIA G-040W-Q has a vulnerability of authentication bypass, which allows an unauthenticated remote attacker to bypass the authentication mechanism to log in to the device by an alternative URL. This makes it possible for unauthenticated remote attackers to log in as any existing users, such as an administrator, to perform arbitrary system operations or disrupt service.

Chunghwa Telecom NOKIA G-040W-Q has a vulnerability of insufficient measures to prevent multiple failed authentication attempts. An unauthenticated remote attacker can execute a crafted Javascript to expose captcha in page, making it very easy for bots to bypass the captcha check and more susceptible to brute force attacks.

If Security Hardening guide rules are not followed, then Nokia WaveLite products allow a local user to create new users with administrative privileges by manipulating a web request. This affects (for example) WaveLite Metro 200 and Fan, WaveLite Metro 200 OPS and Fans, WaveLite Metro 200 and F2B fans, WaveLite Metro 200 OPS and F2B fans, WaveLite Metro 200 NE and F2B fans, and WaveLite Metro 200 NE OPS and F2B fans.

The signature check in the Nokia ASIK AirScale system module version 474021A.101 can be bypassed allowing an attacker to run modified firmware. This could result in the execution of a malicious kernel, arbitrary programs, or modified Nokia programs.

The bootloader in the Nokia ASIK AirScale system module (versions 474021A.101 and 474021A.102) loads public keys for firmware verification signature. If an attacker modifies the flash contents to corrupt the keys, secure boot could be permanently disabled on a given device.

A vulnerability exists in Nokia’s ASIK AirScale system module (versions 474021A.101 and 474021A.102) that could allow an attacker to place a script on the file system accessible from Linux. A script placed in the appropriate place could allow for arbitrary code execution in the bootloader.
