How the Exploit Works

The exploit works by an attacker sending a “reassoc response” frame including a maliciously crafted RIC_DATA element to the target WLAN firmware. When the firmware attempts to process this frame, it leads to a transient DOS condition, causing system instability or temporary unavailability. This condition might allow a skilled attacker to compromise the system or leak sensitive data.

Conceptual Example Code

While the specific details of exploiting this vulnerability are not public, a conceptual example might look something like this:

# Send a maliciously crafted "reassoc response" frame to the target
echo -e "\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00" | nc -u target.example.com 12345

This command uses echo to send a binary string (representing a malformed “reassoc response” frame) to the target system over UDP (port 12345). Note that this is a conceptual example and the real-world exploit would likely require a more sophisticated approach.
