How the Exploit Works
The stack buffer overflow vulnerability arises when the software does not properly handle user-supplied input, resulting in overflow of the stack buffer. This overflow can subsequently corrupt other data and execute malicious code. In the case of CVE-2025-53418, an attacker can send specially crafted input to Delta Electronics COMMGR that exceeds the capacity of the stack buffer, thereby triggering the overflow and potential execution of malicious code.
Conceptual Example Code
Here is a conceptual example of how the vulnerability might be exploited using an HTTP request. Note that the specific details of the malicious payload would depend on the target system and the objectives of the attacker.
POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_payload": "A long string of characters exceeding the stack buffer size" }In this example, the “malicious_payload” is a string of characters intentionally designed to overflow the stack buffer, potentially leading to execution of malicious code. Please note that this is a conceptual example and the actual exploit code might look different.
Mitigation
Users should immediately apply the vendor-provided patch to remediate this vulnerability. If this is not possible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation methods to monitor network traffic for suspicious activity. It is also recommended to limit exposure of the vulnerable system to the internet and restrict access to trusted users only until the patch is applied. Regularly updating and patching systems can significantly reduce the risk of such vulnerabilities.
