AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2025-15357 is a command injection vulnerability in the D-Link DI-7400G+ router firmware version 19.12.25A1. It occurs due to improper validation of user input in HTTP GET requests to the /msp_info.htm endpoint, specifically the flag=cmd parameter. Attackers can send specially crafted requests that inject arbitrary system-level commands remotely without authentication, exploiting the device. [1, 3]
How can this vulnerability impact me? :
This vulnerability allows remote attackers to execute arbitrary commands on the affected device without authentication. This can compromise the confidentiality, integrity, and availability of the router, potentially leading to unauthorized control, data exposure, or disruption of network services. [1, 3]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by monitoring HTTP GET requests to the endpoint `/msp_info.htm` with the parameter `flag=cmd`. Suspicious or unexpected commands in this parameter may indicate exploitation attempts. A practical detection method is to capture and analyze network traffic for requests containing `/msp_info.htm?flag=cmd` with unusual or suspicious payloads. For example, using tools like curl or wget to test the endpoint with benign and malicious payloads can help verify if the system is vulnerable. Example command to test the endpoint: `curl -v 'http://<router-ip>/msp_info.htm?flag=cmd&cmd=whoami'`. Additionally, network intrusion detection systems (NIDS) can be configured to alert on HTTP requests containing this pattern. [1, 3]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include restricting access to the affected device's management interface from untrusted networks, such as the internet, by using firewall rules or network segmentation. Since no known countermeasures or patches are available, it is recommended to replace the affected D-Link DI-7400G+ device with an alternative product. Monitoring for exploitation attempts and disabling remote management if possible can also reduce risk. [3]
