Overview
The vulnerability identified as CVE-2024-51982 is a serious security threat that can potentially compromise systems or result in data leakage. The threat affects devices that can be connected through TCP port 9100. An attacker who exploits this vulnerability can crash the target device by issuing a misconfigured Printer Job Language (PJL) command, causing the device to reboot. This vulnerability matters because it can lead to persistent disruptions and potential system compromise.

How the Exploit Works
The exploit works by an unauthenticated attacker connecting to the TCP port 9104 of the target device. The attacker then issues a Printer Job Language (PJL) command with a malformed FORMLINES variable set to a non-number value. The malformed PJL command causes the target device to crash and reboot. The attacker can repeatedly issue the command to continuously crash the device, potentially leading to system compromise or data leakage.
Conceptual Example Code
Assuming the attacker has network access to the target device, a conceptual example of how the vulnerability might be exploited with a PJL command is:
echo -e "\033%-12345X@PJL\r\n@PJL SET FORMLINES=NOT_A_NUMBER\r\n\033%-12345X" | nc target_device_ip 9100In this conceptual example, `NOT_A_NUMBER` is the non-number value set for the FORMLINES variable, `nc` is the netcat command used for reading from and writing to network connections, and `target_device_ip` is the IP address of the target device.
