AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability exists in the Wavlink WL-WN570HA1 device firmware version R70HA1 V1410_221110, specifically in the function set_sys_cmd within the file /cgi-bin/adm.cgi.
The issue is a command injection vulnerability caused by improper handling of the argument 'command'. This allows an attacker to remotely execute arbitrary commands on the device.
The vulnerability has been publicly disclosed and the affected firmware version has been removed from the vendor's website. The affected products are no longer supported.
How can this vulnerability impact me? :
An attacker exploiting this vulnerability can remotely execute arbitrary commands on the affected device.
This can lead to unauthorized control over the device, potentially allowing the attacker to disrupt device functionality, access sensitive information, or use the device as a foothold for further attacks within a network.
Since the device is no longer supported, no official patches are available, increasing the risk if the vulnerable firmware is still in use.
What immediate steps should I take to mitigate this vulnerability?
The affected firmware version R70HA1 V1410_221110 for the Wavlink WL-WN570HA1 has been removed from the vendor's website.
Since the product is no longer supported by the maintainer, the immediate mitigation step is to discontinue use of the vulnerable device or firmware.
Consider replacing the device with a supported model or isolating it from untrusted networks to prevent remote exploitation.
