Executive Summary

CVE-2025-9580 is a command injection vulnerability in the LB-LINK BL-X26 router version 1.2.8. It occurs in the HTTP Handler component at the /goform/set_blacklist endpoint, where manipulation of the mac argument allows an attacker to execute arbitrary operating system commands on the device. The attack can be launched remotely by sending a specially crafted HTTP POST request. This happens because of insufficient input validation and authorization controls in the router's firmware. [1]

Impact Analysis

This vulnerability can allow an attacker with authorized access to remotely execute arbitrary OS commands on the affected router. This could lead to unauthorized control over the device, potentially allowing the attacker to disrupt network operations, intercept or manipulate network traffic, or use the device as a foothold for further attacks within the network. [1]

Detection Guidance

This vulnerability can be detected by monitoring for HTTP POST requests to the endpoint /goform/set_blacklist on LB-LINK BL-X26 routers version 1.2.8. Specifically, look for suspicious or malformed requests that include the mac argument potentially containing command injection payloads. Network intrusion detection systems (NIDS) can be configured to alert on such requests. Additionally, you can use tools like curl or wget to manually test the endpoint by sending crafted POST requests to see if command injection is possible. Example command to test (replace <router_ip>): curl -X POST http://<router_ip>/goform/set_blacklist -d "mac=;id" [1]

Mitigation Strategies

Immediate mitigation steps include restricting access to the affected router's management interface to trusted networks or IP addresses only, disabling remote management if enabled, and monitoring for suspicious activity targeting /goform/set_blacklist. Since the vendor has not provided a patch or response, consider isolating the device from untrusted networks. Applying network-level protections such as firewall rules to block unauthorized HTTP POST requests to the vulnerable endpoint can also help reduce risk. [1]
