Detailsinfo

A vulnerability, which was classified as critical, was found in LB-Link BL-CPE300M AX300 4G LTE Router 01.01.02P42U. This affects an unknown functionality. The manipulation with an unknown input leads to a user session vulnerability. CWE is classifying the issue as CWE-1018. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The LB-Link BL-CPE300M AX300 4G LTE Router firmware version BL-R8800_B10_ALK_SL_V01.01.02P42U14_06 does not implement proper session handling. After a user authenticates from a specific IP address, the router grants access to any other client using that same IP, without requiring credentials or verifying client identity. There are no session tokens, cookies, or unique identifiers in place. This flaw allows an attacker to obtain full administrative access simply by configuring their device to use the same IP address as a previously authenticated user. This results in a complete authentication bypass.

This vulnerability is uniquely identified as CVE-2025-57278 since 08/17/2025. The exploitability is told to be difficult. 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 09/09/2025).

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