Overview
CVE-2025-3496 is a critical vulnerability that allows an unauthenticated remote attacker to trigger a buffer overflow via the Bluetooth or RS-232 interface. This could potentially lead to unexpected system behaviour or Denial of Service (DoS). As a consequence, systems could be compromised, and sensitive data could potentially be leaked, resulting in a significant impact on security and privacy.

How the Exploit Works
The exploit works by an attacker sending a specially crafted packet via Bluetooth or the RS-232 interface to the target system. This packet causes a buffer overflow, which can lead to a system crash (DoS) or, in some cases, allow the attacker to execute arbitrary code.
Conceptual Example Code
Here is a high-level pseudocode example of how an attacker might trigger this vulnerability:
function exploit(target_address) {
// Construct a malicious packet that will cause a buffer overflow
var malicious_packet = construct_malicious_packet();
// Send the malicious packet to the target via Bluetooth or the RS-232 interface
send_packet(target_address, malicious_packet);
}
function construct_malicious_packet() {
// The actual construction of the malicious packet would depend on the specifics of the vulnerability and the target system
return "MALICIOUS_PACKET_DATA";
}Mitigation Guidance
Affected users should apply the vendor patch as soon as possible to address this vulnerability. As a temporary mitigation, users can also use a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) to detect and block attempts to exploit this vulnerability.
