What is CVE-2023-26801?

The LB-LINK BL-AC1900, BL-WR9000, BL-X26, and BL-LTE300 models have been found to have a command injection vulnerability that can be exploited through specially crafted requests to the /goform/set_LimitClient_cfg endpoint. The vulnerability arises from improper input validation of the mac, time1, and time2 parameters, potentially allowing an attacker to execute arbitrary commands on the affected devices. This poses significant risks to network security, making it crucial for users to review their configurations and update to secure versions.
